After a terrible battle, Navy SEAL Ocean “Blue” Beckett is captured and tortured by the enemy. Battle fatigued with PTSD, Blue is rotated out of his unit to teach at Panama City, Florida. He’s supposed to get his shit together, see a therapist about his condition and work his way back to active duty. But he’s struggling every day to keep his thoughts from overrunning his common sense and his sanity is tested by Navy diver, Petty Officer Charlotte Coventry. She seems to see right into his soul, but if he steps over the line, he’s not only risking his career, but his heart.

Charlie sees Blue’s pain and she can’t help but respond. She’s been in the same position as he is and her own demons still haunt her. So, it seems like a boneheaded move for her to risk her dream of becoming a Master Diver, a coveted position, for an affair with her off-limits instructor. But even as the forbidden relationship tempts her, Blue shows her exactly the kind of hero he is and crossing the line becomes almost impossible as it dawns on her bit by bit that she knows how to heal him and in the process, maybe he could save her, too. Will her heart rule her head? While they work to overcome their trauma, Blue’s past comes back to haunt him in a violent way, putting Charlie’s life in danger. After all that they have to overcome, will this tear them apart?
