Jonah has led countless angels into battle, and seen too many of them slaughtered. When an enemy blow severs his wing and knocks him into the sea, he's ready to let the sea have him. But Anna has different plans.

Anna is a Daughter of Arianne — a direct descendant of the mermaid whose poignant legend and lore is much darker and more complex than the human-made fairytale. Tragedy and isolation are her destiny, but she will risk it all to convince the powerful warrior to embrace what she doesn't have—time.
