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.
