Graduate student Autumn McShane has had her share of heartbreak. She’s been abandoned and betrayed and she lost her beloved mother in a tragic car accident five months ago. That loss damaged her body and fractured her spirit but she’s learning to recover, until her ex-boyfriend returns to town, intent on making her life miserable.

Declan Fraser hates her ex as much as Autumn does, but the last thing she needs is to put her trust in the hands of another man, especially one like Declan: his hard body and lulling Irish accent makes more than a few girls weak-kneed. The talented rugby player is rude and sarcastic, with tattooed, muscular arms and a cocky attitude, but he's the only one who can help Autumn win an ill-advised bet that, if lost, could cost her more than she's willing to pay. The reluctant alliance between Declan and Autumn stirs up cravings she doesn't want to admit, but Declan is a hard man to resist.

Just when Autumn starts letting down her carefully constructed walls to the sexy bad boy, he betrays her when she needs him most. Autumn suspects Declan has secrets, and she is determined to uncover what drove him away from her, even if that means fraternizing with the enemy. But will the truth return Declan to her arms or add to the scars on her heart?
