Who knew one kiss could cause so much trouble? Now these lifelong enemies will have to work together to set the story straight—and try not to kill each other while they're at it. Just one Kiss. That's all it's supposed to be. A dare is issued, a challenge accepted, and now these rivals have to kiss. No biggie, right? Except it becomes a big deal when Mara's crush finds out and now she needs Ryan's help to make things right. But Ryan has issues of his own. And those issues? They require the help of a girl. Preferably Mara. After all, everyone already believes they've kissed. Why not let them think she's his girlfriend too?
