Fifteen year old Lisi Reynolds likes to fib. Just little ones. What's wrong with that? Everyone lies, don't they?

With best friend Josh's traumatic love life, a shopping-addicted mother and Chad Swanning oblivious to her existence, how else is Lisi supposed to survive, if not with a little truth-stretching?

But when a rare mammatus cloud over the Globe puts Lisi in her delectable English teacher Miss Mint's shoes, living the ultimate lie proves irresistible. There's just one catch: Miss Mint wants her life back. And she won't get it until Lisi starts telling the truth. But with a cool house, hunky fiancé and the chance to confront bully Alicia and win Chad's heart, why would Lisi give it all up, to be honest?
