It's Not Me, It's You - by Alex Light

The snark and instant chemistry of Better Than the Movies meets the indulgent summer fun and family hijinks of The Summer of Broken Rules in this compulsively readable rom-com from Alex Light, author of The Upside of Falling . Jackie Myers is a fraud. Or she might be a genius - the jury 's still out. The thing is, she secretly runs pleasebreakmyheart , a gone-viral account aimed at breaking hearts and ending relationships. And she just used it to break up her insufferable eternal nemesis's picture-perfect relationship. Wilson is the buttoned-up, type A assistant manager of her nightmares - but it turns out he 's also, apparently, a really great boyfriend. So with her conscience (and paycheck) on the line, Jackie decides there 's only one thing to do: She 's going to help Wilson win his ex-girlfriend back. Which should be easy, considering Jackie hates him, right?
