The titles and plots are below!
Then Sean dumps Emily on moving day and her father announces he's staying behind in Chicago "to tie up loose ends," and Emily decides that what a nice girl needs to do is to stop being nice.
She reconnects with her best friends in Boston, Josie and Lucy, only to discover that they too have been on the receiving end of some glaring Guy Don'ts. So when the girls have to come up with something to put in the senior class time capsule, they know exactly what to do. They'll create a not-so-nice reference guide for future generations of guys -- an instruction book that teaches them the right way to treat girls.
But when her friends draft Emily to test out their tips on Luke Preston -- the hottest, most popular guy in school, who just broke up with Josie by email -- Emily soon finds that Luke is the trickiest of test subjects . . . and that even a nice girl like Emily has a few things to learn about love.
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."
And then there's Will. Gorgeous, unattainable Will, whom Kate acts like she can't stand even though she can't stop thinking about him. When Will starts acting interested, Kate hates herself for wanting him when she's sure she's just his latest conquest.
Kate figures that the only way things will ever stop hurting so much is if she keeps to herself and stops caring about anyone or anything. What she doesn't realize is that while life may not always be perfect, good things can happen -- but only if she lets them....
