The island was not on any map. Maya knew this because she had checked three maps in the lighthouse, and none of them showed it.

Tomas tied the boat to a rock. The sailor did not look afraid, but he did not look happy either. "We should wait for morning," he said.

Maya looked at the lighthouse. Its light was steady now, turning slowly across the water. "Someone is awake," she said. "They know we are here."

They walked up from the shore. The stones were wet and sharp. Behind them, the sea was still angry. Ahead, between the trees, small lights began to appear.

It was a village. Not a big one: perhaps twenty houses, a school, a well and a long low building with smoke coming from the chimney. No cars. No road. Just the island, the lighthouse, and the people.

An old woman met them at the edge of the village. She wore a heavy coat and carried a lamp. "You came through the storm," she said. "That takes courage."

"My grandfather left me a map," Maya said. "It led us here."

The woman looked at the anchor on Maya's map, then at the compass in her hand. "I knew your grandfather," she said. "He was a good man. He asked too many questions."

She led them to the lighthouse. Inside, the walls were covered with maps: some old, some new, some drawn on the backs of letters. Maya saw islands she had never heard of. Lines crossed the sea like handwriting.

"Your grandfather believed that every map is a story," the woman said. "And every story has a door."

She gave Maya a small notebook. On the first page was a map of the village. On the second page was a map of the lighthouse. On the third page was a map of a room Maya had never seen.

"What is this place?" Maya asked.

The old woman smiled. "A school for keepers," she said. "We teach people how to keep a light. Not only the one in the tower."

Maya looked at the notebook. Her wisdom was still small, but her courage was growing. She turned to the next page.

It was blank.

"Good," said the old woman. "You will need room for your own story."

A thought to keep

Every map is a story. Every story has a door.
