Showing If That Breathes Fire, We're Toast by Jennifer J. Stewart

Rick is none too happy when his mother ups and drags him from San Diego, where he had friends, to Arizona, where he knows no one except for Fat Boy, his cat. He dreads a long, dull, boring summer, until the day Madam Yang arrives on the scene. Madam Yang is no fairy godmother. She's a fire-breathing, princess-chasing, time-traveling, hotheaded dragon, with her own ideas on just about everything. Now Rick and his neighbor Natalie are in the hot seat. Will the two of them be able to keep Madam Yang happy, or will their goose be cooked?
