Ember, Miles, and Sam have been called home—only home is a place none of them have ever been before. The choices they make will not only determine their own futures but will also have vast and permanent consequences—they will either restore a cosmic balance or destroy the dams that separate two worlds, ending them both. Ember was called because she belonged, Miles because his mother belonged, and Sam . . . well, Sam arranged his own invitation.

The Fountain itself is beautiful and alluring—yet so is the light of an anglerfish. Hidden below the surface, the world of the Fountain is vast: unexplored and unmapped and full of wild things—leviathan and tiny, scuttling things and all manner of creature in between. There are other entities as well, entities that haunt and hunt in the Fountain, because it rewards nearly as often as it punishes, and it has been punishing the greedy and merciless and cruel for a very long time. For those, the Fountain becomes a prison.

The borders between our world and the world of the Fountain are already porous. If the balance between them is upset and control of the Fountain is lost, the consequences will be rapid, merciless, and world-ending. In every timeline that has been or will be, everywhere that water stands in our world will become a passageway for the violent damned to enter ours from the Fountain. For Ember, Miles, and Sam, all from different times, what starts as a journey to take control of their lives quickly becomes a quest to save—or destroy—both worlds, depending on whom you ask.

Rising star and Bram Stoker Award-winning author, Lora Senf has created a gorgeously written, pitch-black fantasy that will transport readers to a world that is as beautiful as it is horrifying and will keep readers on their toes as they devour it page by page.
