In Too Deep by Kira Sinclair

He didn't want to need her…

Trouble just walked onto Knox McLemore's ship — trouble with lush curves, red hair, and an uptight attitude that both grates on his nerves and heats his blood. But former Navy SEAL Knox knows all about control. Especially when this sexy nautical archaeologist is the only thing standing between his diving team's claim on a famous shipwreck and utter ruin.

Dr Avery Walsh is grateful her icy persona hides the effect intimidating (and way-too-hot) Knox has on her. For two people who don't trust — or even like — each other much, the physical chemistry between them is unbelievable. But getting in too deep with Knox is the last thing Avery needs. Because she has a job to do and dark little secrets to hide.
