"To sell a book, you need a description on the back. So here's mine: My name is Fiona Loomis. I was born on August 11, 1977. I am recording this message on the morning of October 13, 1989. Today I am thirteen years old. Not a day older. Not a day younger."

Fiona Loomis is Alice, back from Wonderland. She is Lucy, returned from Narnia. She is Coraline, home from the Other World. She is the girl we read about in storybooks, but here's the difference: She is real.

Twelve-year-old Alistair Cleary is her neighbor in a town where everyone knows each other. One afternoon, Fiona shows up at Alistair's doorstep with a strange proposition. She wants him to write her biography. What begins as an odd vanity project gradually turns into a frightening glimpse into a clearly troubled mind. For Fiona tells Alistair a secret. In her basement there's a gateway and it leads to the magical world of Aquavania, the place where stories are born. In Aquavania, there's a creature called the Riverman and he's stealing the souls of children. Fiona's soul could be next.

Alistair has a choice. He can believe her, or he can believe something else...something even more terrifying.
