Yield To Me by Sarah Castille

No-holds-barred attraction...

Amateur MMA fighter, Marcy Foster is determined to win the state championship. But dark secrets and a broken trust mean there's one submission she just can’t master. Fortunately Club Excelsior has hired a coach who knows all the right moves.

Sexy, confident and commanding, fight consultant Jax demands control, both in and out of the ring. But once he has Marcy against the ropes, Jax knows he’s in too deep. He has the dominance to give her what she needs, but once he unleashes her hidden passions, there's no going back.

Under Jax's skilled hands, Marcy submits to her deepest desires. But when her personal and professional worlds collide, she is forced to face a brutal truth — yielding to her darkest needs may be the one thing that costs her the fight...and her heart.
