An army of the drowned dead, family betrayal, an exiled witch who doesn't know she has power--or that enemies are lurking all around her, spying on her. Follow Kassandra as she discovers who and what she is in this moving underwater fantasy.

Kassandra comes from the sea, but she has no memory of saltwater, seagulls, or an incoming tide. She's never seen an ocean, never heard the thunder of surf. She's an exile, betrayed by her own family, sent as far from the sea as they could arrange--somewhere in the middle of Nebraska.

Everything changes the day she drowns in Red Bear Lake, and discovers she can't really drown. Not in the way everyone else can. Then a two-thousand year old king wakes inside her head and turns out to be a prodigy with mathematics. Kassandra cries for the first time in her life, and learns that her tears are doorways for calling things from the sea. With clues from summoned sea-demons and the voices in her head, Kassandra sets out to find out what the hell is going on...and discovers she's a prisoner, trapped between a murderous grandfather who controls an army of the drowned dead, river witches who spy on her through the plumbing, and Ms. Matrothy, the Girl's Department Director, who's been trying to kill her since she was four.
