Night Tide (Wraith Kings, #1.5)

Something hunts the surf at night, luring villagers to their deaths with a lullaby of sorrow and the torture of nightmares.

Blessed with the gift of water-sight, Zigana Imre senses the presence of an ancient predator drawn by a hunger for human flesh sweetened by grief. With the help of a child of earth, she will battle a spawn of the sea to protect a loved one and save a man who will one day fight to save a world.

Originally published in the 'Teeth, Long and Sharp' anthology, Night Tide is a stand-alone novella that takes place in the world of the Wraith Kings series.
