The ocean is dying.Megan Delaney, a brilliant but headstrong oceanographer, has devoted her life to saving the ocean.When she's assigned to a two-month expedition studying a hostile remote island that rose from the sea after a massive earthquake, she expected long hours, rough weather, and maybe a few scientific breakthroughs-not to be stranded and alone with her impossibly broody boss on said island.But when a violent storm sends them both overboard, survival is the least of Megan's worries.Because something is happening to Creatan.And it's all because of her.He came to the surface world to save his people, not find a mate. But Megan's scent awakens something in him. Something his people haven't seen in over five years.She isn't supposed to be his. She isn't even supposed to know his kind exists. But his control is slipping, his rut is rising and every moment near Megan is a battle he's losing, and it could destroy his people's existence.In a world where humans and sea shifters are enemies, their forbidden bond might be the only thing strong enough to save their worlds...or drown them completely.
