Ripped (The REAL series)

The fifth book in the New York Times new adult series that began with Real.

A ripped rock star with attitude. An ex-girlfriend with a reckless plan.
 
 
Pandora assumed getting her heart broken by her bad boy ex could only happen once--until Mackenna Jones comes back to town for the biggest concert of his career. They say girls are getting pregnant just thinking about the Crack Bikini tour and it's destined to be a huge hit.
 
Oh, it'll be a hit alright--when Pandora comes out swinging. She and her friend Melanie are determined to humiliate him onstage. But when they're caught by security and her ex is summoned, Mackenna decides not to press charges if she'll join him on tour and follow certain conditions--rules designed to give him the upper hand and keep her in close contact with him once again. Soon, the passion they once shared is reignited, and no matter how much Pandora wants to hate him, her hard exterior starts to crack.  
 
And worse: Mackenna knows it, too. But he hasn't uncovered all her secrets...
