The bottle was not warning me about the rain.
It showed how high the sea had reached during an earlier tide, and the white salt line around its middle had been left in the fork of the palm above my head.
Our shelter stood lower than that mark.
I woke Toma first and pressed Ari into his arms while I pulled Leni to her feet.
The air smelled of wet leaves, and warm water already covered the place where we had buried the cracker wrappers.
“We have to go higher,” I said.
“There isn’t higher,” Toma answered.
He was right about the island.
I tied the four palm-strip bracelets together with another length of leaf, leaving enough space for us to move in a line, and pushed the green bottle beneath the knot at my waist.
We climbed through the palms until the ground ended at a ridge of roots no taller than my knees.
By dawn, waves were crossing the island from both sides.
Beyond the eastern beach, a narrow strip of dark reef appeared between us and the next island.
It had been underwater the day before.
I gave Toma the seat cushion and placed Ari across it, then made Leni hold the back of my waistband.
The water between the islands reached my chest in the deepest section, and the current pulled hard enough to turn the cushion sideways.
Toma shouted that he could not hold it.
I wrapped the bracelet line around my wrist, grabbed the cushion with both hands, and kept walking until coral scraped the skin from my toes.
Halfway across, I looked back.
Our shelter had collapsed.
The leaves floated through the palms, and the hollow where we had slept was gone.
I faced the next island and pulled the other three children after me.
We did not return.
The second island was longer, but it had almost no shade near the beach.
By the time we reached dry sand, Ari’s face was hot, Leni was coughing seawater, and Toma had bitten through his lower lip without noticing.
I untied us and counted the bracelets.
Four.
Then I counted the children.
Four.
The green bottle was still trapped at my waist, but it held only a finger of warm water mixed with sand.
I poured it over Ari’s lips.
He swallowed once.
The sun climbed, and the beach became too hot to kneel on, so I dragged everyone beneath a group of short palms and searched for anything that might hold rain.
There were coconuts everywhere.
Most had split open or turned gray inside, and the first one I tried to break left a cut across my palm.
Toma carried three more to a flat stone anyway.
He struck them until his arms shook.
One finally cracked.
The liquid inside smelled sour.
I threw it beyond the trees before Leni could drink it.
She watched where it landed.
“I’m not thirsty,” she said.
Her tongue was white.
Sometime that afternoon, I found a fallen trunk with a hollow center protected by overlapping bark.
When I pushed my fingers inside, they came back wet.
The water smelled like wood, not salt.
I filled the green bottle slowly, waiting after every few spoonfuls for the hollow to refill, and gave the first drink to Leni.
She took too much.
I pulled the bottle away, and she slapped my wrist with both hands.
Then she turned her face toward the trunk and cried without making a sound.
I waited.
When her breathing slowed, I gave her one more mouthful.
We stayed beside that trunk for the rest of the day.
Toma gathered broad leaves, though most were too stiff to bend, and I built a low roof against the shaded side of the palms.
Ari slept with his mouth open.
Each time he stopped making noise, I touched his ribs until he moved again.
Near sunset, birds crossed above us in a line and continued toward the eastern horizon.
I watched them until they disappeared.
Grandma had once told me that birds returned to land before dark, but I did not know whether she meant all birds or only the ones near our home.
I placed the bottle in the hollow trunk and scratched a line in the bark at the water level.
By morning, the level had risen.
For the first time since the ferry, every child drank twice.
Toma found small shellfish beneath rocks, and I used a sharp piece of coral to open them.
The meat was almost too small to hold.
We ate it anyway.
A white crab stole one empty shell and dragged it backward through the sand while Leni followed it for several steps.
She came back carrying a feather.
It was not useful.
She tucked it into her bracelet.
That afternoon, I arranged dark branches on the beach in four long lines.
From the ground, the mark looked enormous.
From the top of the tallest rock, it almost disappeared against the trees.
I moved every branch closer to the water, then added pale coral around the edges until my shoulders burned.
Toma helped for a while.
Later, he sat beside Ari and rubbed a smooth stone across his own knee again and again.
A plane crossed far to the west before sunset.
None of us shouted.
I held my shirt above my head, but the plane never turned.
After dark, clouds covered the stars.
The air stayed hot, and the smell of the sea became stronger as the wind rose.
I moved the green bottle from the trunk to the shelter and wrapped its neck inside my shirt.
When the rain began, it came sideways.
Our roof lifted once, settled, then tore free from the palms.
Toma grabbed Ari.
I grabbed Leni.
The next wave reached the hollow trunk and filled it with sand.
I tried to dig the opening clear with my cut hand, but water pushed bark and dead insects back into the hole.
The freshwater was gone.
Another gust rolled the green bottle across the ground.
I lunged for it and caught only the end of my shirt.
The bottle struck a root, spun into the flooded brush, and disappeared.
By morning, the signal on the beach was scattered.
The branches had floated inland, the pale coral had sunk into soft sand, and the shelter roof hung from a palm forty steps away.
We had gained water, shade, and a sign for the aircraft.
In one night, we lost all three.
I searched for the bottle until the sun reached the tops of the palms.
Toma followed me with Ari while Leni stayed near the fallen trunk.
We checked roots, pools, piles of grass, and the narrow places where floating leaves had gathered.
I found a broken comb, one yellow sandal, and a plastic lid with teeth marks around the edge.
The bottle was gone.
When we returned, Leni was sitting in the same place.
She had pushed the feather halfway into the sand.
“I heard Grandma,” she said.
I looked toward the water.
There was no boat.
“What did she say?” Toma asked.
Leni shrugged.
“She was counting.”
I tore the cleanest section from the ruined roof and spread it beneath Ari.
Then I counted us aloud.
Four.
The fourth morning brought no rain.
I squeezed moisture from the bark into Ari’s mouth and gave the others pieces of soft coconut no larger than my thumb.
Before noon, Toma stopped asking for water.
That frightened me more than when he asked.
I climbed a leaning palm and saw two more islands to the east.
One was a thin ring of sand.
The other had darker trees and a beach wide enough to reflect the sky.
Between us and the first island, the water was broken by pale patches that appeared and vanished with the waves.
I waited until late afternoon, when the sea drew back from the reef.
We tied the bracelets together again.
This time, I carried Ari inside my shirt with his head beneath my chin, and Toma held Leni’s hand.
We stepped into water that looked shallow but dropped without warning around holes in the coral.
At the first hole, Leni slipped.
I caught her bracelet line and pulled until she surfaced, coughing against my shoulder.
A small fish was trapped inside her collar.
Toma removed it and threw it back.
We continued.
The first island had no trees tall enough for shade and no hollow trunks.
It held only shells, bird droppings, and a dead section of reef warmed by the sun.
Crossing to it had not brought us closer to food or water.
It had changed the direction of the current.
Floating grass now moved past us toward the larger island.
So did a red candy wrapper.
It opened and closed on the water exactly as the wrapper near the ferry had done.
I watched it drift through a narrow channel on the southern side of the reef.
The channel was too deep to cross before low tide.
We waited.
Toma picked at the dried blood on his lip, Leni placed shells in a crooked row, and I kept Ari in the small patch of shadow behind my back.
When the reef emerged again, I entered the channel first.
The bottom was uneven, but the current pushed toward the larger island instead of away from it.
I put Leni on the seat cushion with Ari and told Toma to kick behind them.
He said he could.
After several strokes, his hands slid from the cushion.
I pulled him up by the bracelet line.
For a few seconds, all four of us drifted sideways.
Then my feet touched rock.
I pushed.
Toma pushed.
Leni kicked with one sandal still on her foot.
The cushion struck sand.
We crawled onto the third island sometime before dark.
The beach was scattered with storm debris carried through the same channel.
Near a pile of branches, Toma found the green bottle.
Its cap was missing, and one side had been scratched white by coral, but the bottle itself was not broken.
He held it against his chest.
“It came with us,” he said.
I did not tell him that the current had carried it.
We followed bird tracks into the trees and found several shallow stone basins filled with rainwater.
Leaves floated on top, along with insects and a layer of green dust.
I strained the water through my shirt and filled the bottle.
It tasted bitter.
Nobody refused it.
For the next two days, we stayed on that island.
I rebuilt the beach signal each morning, using driftwood for the number four and dark cloth from a torn bag to make its shape visible.
At midday, we rested because the sand burned through our clothes.
At night, I slept in pieces while Toma held the bottle against his stomach.
Leni’s cough faded.
Ari began crying louder.
The sound annoyed Toma.
It made me breathe easier.
On the seventh day, I climbed a palm to look beyond the reef.
My left foot slipped against a broken stub, and the wood cut beneath my smallest toe.
Blood ran down the trunk and made my heel slick.
I lowered myself with both arms and landed badly.
Toma brought the bottle, but I would not use drinking water to wash the cut.
I packed it with clean sand first, then wrapped it in woven leaves the way Grandma had wrapped a burn on Leni’s arm the summer before.
The bandage tightened when it dried.
I could still stand.
That evening, a boat appeared beyond the western reef.
It was small and white, with a dark roof and a motor loud enough for us to hear between the waves.
Toma ran into the water.
I grabbed the back of his shirt before he reached the drop-off.
We shouted until our throats hurt.
I waved my shirt.
Leni raised the green bottle over her head.
The boat continued south.
For several minutes, we could still see its wake.
Then there was only open water.
Toma sat where the waves reached his knees.
“They looked at us,” he said.
I pulled him back to dry sand.
He would not release the bottle.
That night, no one asked when another boat would come.
I divided the remaining water into four portions and made each child drink before I touched mine.
A moth landed on Ari’s forehead.
Leni removed it carefully and carried it outside the shelter.
Before dawn, I heard an engine again.
The sound faded before I reached the beach.
I climbed the same palm despite my foot.
From above the lower leaves, I could see that the distant boat was circling a reef channel instead of leaving.
Orange moved across its deck.
I pulled off my shirt, wrapped one arm around the trunk, and waved with the other.
The boat turned toward the island.
Below me, Toma began counting.
“One,” he called.
He pointed to Ari.
“Two.”
He pointed to Leni.
“Three.”
Then he looked up at me.
“Four.”
The boat stopped outside the reef, and three people entered a smaller craft.
They wore orange vests.
I kept waving until one of them raised both arms.
Only then did I climb down.
My foot would not take my weight when I reached the ground, so Toma stood beneath my shoulder while Leni held Ari.
The small craft crossed the channel and scraped onto the sand.
One rescuer moved toward us quickly, but I stepped between him and the other children.
“How many?” he asked.
“Four,” I said.
He looked behind me, counted, and spoke into a radio.
Another rescuer knelt beside Ari and reached for him.
I made her drink from our bottle first.
She understood.
She took one mouthful, handed it back, and waited until I placed Ari in her arms.
On the rescue boat, they wrapped us in silver blankets and gave us small sips from paper cups.
Toma hid the green bottle beneath his blanket because he thought they would throw it away.
A rescuer cleaned my foot while another cut the palm-strip bracelets from the line joining us.
I stopped him before he cut the four separate loops.
“Those stay,” I said.
He left them on our wrists.
The search team had followed storm debris through the outer channels that morning.
The boat we had seen the evening before had reported movement near the island but could not cross the reef before the tide changed.
At first light, the rescuers returned through the southern passage.
They saw my shirt above the palms.
At the hospital, people asked the same questions in different voices.
Who had been with us on the ferry?
When had we last seen Grandma?
Had any other passenger reached the islands?
I answered until my mouth hurt.
Nobody asked me to count the children because all four beds were in the same room.
Toma slept with one hand around the bottle.
Leni placed her feather on Ari’s blanket.
For nine nights, I had touched four bracelets whenever I woke.
On the tenth night, I opened my eyes, saw the three beds beside mine, and let my hands remain under the blanket.
The green bottle is on my shelf now, holding four dry palm strips.
