How to Date Like a Guy: 1. Flirt constantly.2. Keep your options open.3. Don't get attached.Cassie and her two best friends, Greta and Keagan, are so over boyfriends. But just because the girls are anti-boyfriend doesn't mean they're anti-boy. So they make a pact for the summer: They'll each kiss ten different guys before school starts — no commitments, no drama, just fun. Sounds easy enough. Then Cassie meets the perfect guy (nine boys too soon), and the pact starts to seem like a terrible idea. Not to mention Boy Number One turns out to be her best friend's ex. Ugh — Cassie's summer just went from carefree to complicated faster than she can say "heartbreaker."
