He's a monster desperately seeking peace in the ocean's depths. She's the human fighter pilot who crashes into his sea.

Deep space fighter pilot Calla Wren survived a hellish childhood and fought to earn her wings in the Alliance Defense. After a battle with mercenaries leaves her ship badly damaged, Calla crashes on the storm-ravaged moon Iosa and falls into the hands of a band of raiders.

Plagued by memories and nightmares, former elite assassin Vos Turek retired to a new, quiet life on Iosa, searching for peace in the depths of its lavender seas. His hard-won safe haven is threatened when an Alliance Defense fighter crashes into the ocean nearby. The moment he catches the pilot's scent, he knows the gods have sent him his true mate-if he can save her life and earn her trust.

As fiercely independent Calla recovers in Vos's care, they find kinship over their traumatic pasts. Despite Calla's deep mistrust and her determination to return to being a pilot, they are drawn together by a connection deeper than the power of the true mate bond. But when a vicious, vengeful adversary tracks them to Iosa, Calla and Vos must not only survive but confront the ghosts of their pasts that threaten to tear them apart.
