Belong to Me — Shayla Black

She's undercover and in over her head...
When FBI analyst Tara Jacobs' fellow agent and best friend goes missing while investigating a sex ring, Tara goes undercover as a submissive in a Dallas BDSM club called Dominion. But no man can top a woman with Tara's moxie convincingly enough -- until an edgy, dangerous Dom takes control of the scene and sets her heart racing with a single, commanding glance. Too bad he's also the man who stole her innocence years ago -- and the one to whom she will never submit.

He's got everything under control...until he falls for her again.
Navy SEAL Logan Edgington once left the woman he loved to save her life. He knows Tara will never forgive him, but he has no doubt that he possesses the knowledge to master her fears and the strength to guide her through an unfamiliar world of pleasure and pain. He alone can protect her on a dangerous mission that reveals both wicked depravities and terrible secrets. Logan relishes the exquisite torture of holding her again, feeling her uninhibited response. No matter how much Tara insists their fling will end after this mission, he's determined that she will be his again -- and this time, he'll never let her go.
