A ferry brought a thousand dead bodies to the city. Everyone on board drowned—in water that wasn’t there. A tragedy, horrific in itself, may turn out to be only part of a complex ritual capable of plunging the world into chaos.

But even the strongest of them aren’t ready to face an ancient power our world has long forgotten. The closest to the truth unexpectedly come those you wouldn’t expect— a weak psychic, yesterday’s cadet, a blind man, and a woman keeping a terrible secret.
