No man has ever rattled Isabel Ward… until Aiden Hennessy walks through the door of her gym, ownership papers in hand. The former fighter is a lot of things: a single dad, a widower trying to start over, and a watchful presence that knocks her off her very capable feet. And, to make matters worse, she had a crush on him for the entirety of her teenage years. Doodles in her diaries and unsent letters declaring her admiration haunt the absolute crap out of her now that she has to face him every day. No woman has ever tempted Aiden to move on from the memory of his wife… until Isabel. She’s too young, too fiery, too much of everything he should avoid. But avoiding is impossible, just like pretending the blistering chemistry between them doesn’t exist. Now that the unshakeable woman is shaken and the un-temptable man is tempted, Isabel and Aiden will have to decide what they’re willing to risk for a taste of the forbidden.
