As Mt. Pleasant's top weight loss counsellor, Susan Snow is gunning for a promotion. Her only distraction is a mirror she suspects is magic. Angela Marshall can't seem to make a dent in an irksome five pounds she's packed on, and she's willing to cheat her way into ShapeShifters to lose it. Mina Haver risked everything to ensure her daughter could attend school in a bomb-free environment, and she is not about to let a feisty old lady her husband hit with his car get in the way. These three women form an unlikely alliance when they join a ShapeShifters training run. Then Susan gets fired and her daughter gets expelled. Mina becomes the target of a vicious meme. And Angela turns to her new friends from ShapeShifters to find her footing as her son becomes increasingly angry over their move to Canada. Separately, their lives may be derailing, but together Susan, Mina and Angela can survive anything - their erratic children, running mishaps and unraveling identities. Even a mirror with mystical properties cannot tarnish the bond pulling them into an unanticipated future.
