Thank you St. Martin's Press and NetGalley for providing an ARC in exchange for an honest review! 
 Surprisingly, I really enjoyed this book. It's well written, daring, thought provoking and one of a kind story that we don't usually see in a young adult book. For a YA novel, it is a little mature. I don't really mind sex in YA but with the issues tackled here, you must keep an open mind about it. 
 Mercedes / Mercy offers to have sex with virgin guys. She teaches them what to do or not to do on sex so that these guys can give their girlfriends a pleasurable, flawless first time. If you're going to think about it? It's very unusual. She has good intentions of helping them and doesn't want those girls to experience what she'd been experience. Certainly her actions are wrong, ridiculous and stupid. 
 However, I was eager to know the story behind all of it. Which makes me understand her more. She definitely has family issues. Still, there are consequences she had to face and learned her lessons in a hard way. Overall, it is a great debut novel.
