Sharp, sleek, and golden. Like the dagger she has worn since childhood, eighteen-year-old Aeva is all three of these things. But there is something else that this mermaid and her prized weapon share – they are both hunted.
Hidden within the caves off Iceland’s dark shore, Aeva waits to take her place as the next ruler of the Mermaids. But when Aeva uses her potent and alluring song to save a drowning human, she disrupts a delicate balance. Realizing she has unexpectedly bound herself to Gunnar, Aeva is torn between duty and love.
Aeva severs one life to begin another, and soon finds herself not only rejected by the sea, but also stalked by an old enemy. As the worlds of myth and man intertwine, Aeva will challenge fate to protect her own sacred relic and the man she loves.
But legend and lies cast an intricate net. With time and safety quickly unraveling for Aeva and Gunnar, there is only one clear course: Find and defeat Delphine before she can shift again.
