Perfect Addiction

Kickboxing trainer Sienna Lane never thought she'd be training her boyfriend's arch-nemesis, Kayden, in the ring, but then again she never thought she'd catch her boyfriend cheating on her-- with her sister. Out for revenge, Sienna pushes Kayden to his limits during training--determined to have him beat her ex in the championship fight. But as the pressure mounts, and the fight approaches, their passion in the ring is equally matched by their passion between the sheets. And if Sienna can't give up her quest for revenge, she may lose more than the fight--she may lose a chance at real love.
