Saltgrave survives by feeding witches to the sea. When Elowen Grayscale returns home to bury her mother, she learns the truth the town buried with its dead. Beneath the cliffs lives Raylunin, an ancient creature that sustains the coven. In return, one witch is given to it each generation. Elowen has been chosen. The coven hires Ronan Matthias Thorne to make sure the sacrifice happens. Vampire. Enemy of witches. The last man who should be standing at her side. His task is simple. Prepare the witch. Deliver her to the sea. But Elowen's magic is already waking. Raylunin has begun to listen. And the longer Ronan stays close enough to control her power, the harder it becomes to remember she was meant to die. Saltgrave demands devotion. The sea demands blood. Love might be the most dangerous sacrifice of all.
