They all vowed to never date a Mr. Wrong. And it is Winter’s bright idea to go find their Mr. Wrongs and date them by the time they all turn thirty. Simple. Right? It only takes two weeks after they all agree to the challenge for Winter to realize how very, very wrong she is for ever bringing up such a silly idea. It isn’t until Winter accidentally finds her Mr. Wrong teaching a summer class she signed up for at the local university that she begins to reconsider the challenge. Between imagining things she wants him to do to her on his desk to daydreaming about going back to college full-time, Winter is completely turned upside down. Once she learns more about her Mr. Wrong, she lets herself imagine him as Mr. Right...until he reveals a secret that could change everything about love as she knows it.
