"Phoebe finds herself in the awkward position of taking on her friend Max in a debate contest and also helping her best frenemy Dakota regain her confidence. Marigold goes to therapy and reconnects with a friend named Sparkleface McGee who she hasn't seen in 700 years. And both Phoebe and Marigold draw a fun series of comics about their lives. As it turns out, the social lives of a nine-year-old human and a centuries-old unicorn have a lot in common"-- Provided by publisher.
