Sonia is a Hungarian immigrant who is raising her daughter, Mila, on her own in sunny Los Angeles. Her days are a blur of not-quite-illegal business activities, dodging PTA moms, and baking birthday cakes laced with rum. Mila, meanwhile, is juggling violin and swimming lessons and navigating the treacherous social politics of school with the help of a less-than-helpful guidebook on how to be cool in the sixth grade. Sonia is sure that their bond will be enough to satisfy her daughter. But her guarded lifestyle has left Mila lonely, isolated and ready to write herself into a bigger story. When she stumbles across emails between her mother and a man she’s never met, Mila decides to take matters into her own hands and forms a plan that will implode their carefully constructed lives.
