If there's an upside to having your heart broken, it's this: A broken heart makes you brave. The first day of sophomore year doesn't go the way Lucy planned. After a summer apart from her boyfriend, she's ready to greet him with a special surprise and instead gets a shocking one in return: He's breaking up with her. Beyond devastated, Lucy has no idea how she's going to make it through homeroom, let alone the rest of her life. Enter three stunning girls with the unnatural ability to attract boys and an offer Lucy can't refuse: They can heal her heart in an instant. And then she'll be one of them--a member of a sisterhood that is impervious to heartbreak and has access to magic distilled from the tears of brokenhearted boys. But to gain their power, Lucy must get a guy to fall in love with her the old-fashioned way, and then break his heart in the next seven days. While the sisterhood may need another Heartbreaker, Lucy's only desire is to get her ex back.

But how far is she willing to go, and who is she willing to cross to get what she wants?.
