Ain’t No Other Man by Chelsea Davidson

There is a thin line between love and hate. For Allison Walsh, that line was a tightrope hanging a hundred feet in the air, with no safety net to catch her if—or when—she fell.
Ali was barely treading water after losing her big brother, who was her hero and best friend. His sudden death left her to raise her twin nephews when the man that was supposed to share the responsibility with her went MIA after the funeral.
Kade’s MMA training made him a champion, but it never equipped him to fight off the one force beyond his control: his feelings for his best friend’s little sister. He’s sure his demons mean he’s not good enough for her, but he’s going to do everything in his power to conquer them.
When the hunky, tattooed fighter shows up on Ali’s doorstep out of the blue with a bag hanging over his shoulder and a smile that would make a nun blush, he seems different. But after all he’s put her through, Ali’s not in a forgive-and-forget kinda mood.
Will Kade prove that he’s the man worthy of Ali’s heart and trust, or will his past sins determine their future?
