My name is Thea, and I'm a mermaid . . . Siren, Cursed One, Death Bringer, Offering. The titles are endless and none-too-flattering. But another might change everything. Heir. 

Six days ago, I died. Bellamy, my handsome Cephalian trainer, brought me back. Now my life is on hold while the Cephalians debate whether to execute me for endangering their people or train my terrible abilities. After a devastating attack on the Cephalians, Bellamy takes drastic measures to protect me. 

With our worlds on the brink of war, the Drek-toa — dragon-shifters — searching for a new Emissary, and Blight ravaging those I love, the path forward is darker than ever. I must face that darkness, and the responsibility it brings, or the ocean will run red with blood.
