The Mirror Door — Janice Clark

Furious at losing the part of Alice in the school play, Sammy quarrels with her friend Kerri, her mother, and even her cat, Peaches. But Peaches won't let her wallow in self-pity, and nudges her up the magical moonbeam path again. There she faces a more challenging role as she accompanies the cats, Peaches and BB, on a mission. From jabberwocks and carnivorous humpties to hyperactive pixie soldiers and a girl-eating dandelion, there's plenty of excitement along the way. And that's just the beginning. Can Sammy solve a mystery and make peace between two quarreling queens?
