The Dead Tossed Waves is the "unputdownable" companion to The Forest of Hands and Teeth. It takes place in the same world. Gabry, short for Gabrielle, lives with her mother, Mary, in the lighthouse, in the small town of Vista. She's never been out of the town, and has always lived in peace and security from the hungering Mudo - the undead.
One night, with the influence of her best friend Cira, she sneaks out with a group of teenagers, and unwillingly crosses the Barrier, the only thing separating the people of Vista from the Mudo. If one Mudo crosses and infects a human, it will spread, until the whole town is infected, and the Mudo will continue to hunger.
No one notices at first, but a Mudo runs toward the group, and in as little as an hour, Gabry's life falls apart. She finds out her life is not what she thought it was, and she has to face the Forest of Hands and Teeth. This book was heart-breaking, because of the losses Gabry has to endure. But I would highly recommend it. The Dead Tossed Waves will keep you glued from start to finish and will linger around longer than when the last page is turned!
