Because of a Unicorn Incident at her school (it was an accident!), Pip is spending the summer with her Aunt Emma at the Cloverton Clinic for Magical Creatures. At first, it's all fun, games, and chatting with Hobgrackles, but when Fuzzles appear and start bursting into flame at the worst possible places, Pip and her new friend Tomas must take action. Because if the mystery of the Fuzzles isn't solved soon, both magical and unmagical creatures are going to be in a hot mess of trouble.
