Kiddo survives-it's what she does best. And since the world ended, staying alive is a useful skill to have.She and her found-sister, Princess, have created a home for themselves in the forest, and a refuge for the other children who survived the end. Hunting animals, harvesting herbs, treating wounds-this is what Kiddo remembers of her life Before, and little else.But the young man they call the Saver claims to remember everything, even when the rest of the children who survived cannot. He speaks of what came Before when he leads the survivors to his island city, making promises of abundance and hope. But even the Saver's memories can't explain the wrongness of their world. They can't explain why ghosts stream through the woods every night under the same full moon, or why there is a fire in the Burning End of the city that has blazed, unchanged, for nearly a decade.Regardless of what the others believe, Kiddo knows one thing for certain: the city is going to sink someday. She can't explain it-not without remembering. And since the world came to an end, taking memories and lives in equal measure, remembering is the one hardship Kiddo has not been forced to endure.But the city wants Kiddo to remember: at the heart of the fire in the Burning End is a story that only Kiddo can tell-and only Kiddo can finish.
