Heartbreaker (Filthy Dirty Love Book 1) by Stacey Kennedy

Veteran cop, Maddox Hunt, is all about the job. Sure, there are women—lots of women, truth be told—but there’s no one special. Until a one-night stand from his past, rookie Joss O’Neil is assigned to his division. Suddenly, all he can think about is her. The scent of her. The taste of her.
Fresh out of field training, Joss has thrown herself into her job, determined to kick-start her career. And while police work has its thrills, her gorgeous new boss is what really gets her pulse pounding. Too bad he’s nothing but a distraction. Especially since he’s as devastatingly handsome as she remembers, and his sexy smile arrests her heart.
Now that Joss is back in Maddox’s life, he has a plan: satisfy her fantasies and fulfill his every dark desire. Nothing is off limits. Her pleasure is the endgame . . . but even the best-laid plans have a way of falling apart. Despite his best attempts to keep his distance and have things remain only about the pleasure, Maddox soon finds himself breaking the only law he’s set for himself. Don’t fall in love.

The ocean is home to many myths, But some are deadly…
Seven years ago the Atargatis set off on a voyage to the Mariana Trench to film a mockumentary bringing to life ancient sea creatures of legend. It was lost at sea with all hands. Some have called it a hoax; others have called it a tragedy.
Now a new crew has been assembled. But this time they’re not out to entertain. Some seek to validate their life’s work. Some seek the greatest hunt of all. Some seek the truth. But for the ambitious young scientist Victoria Stewart this is a voyage to uncover the fate of the sister she lost.
Whatever the truth may be, it will only be found below the waves.
But the secrets of the deep come with a price.
I’ll recommend the Rachel Grant books. I’ve read and enjoyed all of the set save for the novella.
