Amanda and the Cog-Shifting Imp

The third book in the Far Forth Fables series continues the adventures of Amanda Farlabane, this time with her mom, and the weirdness caused by Amanda's scleeberry tree. To wit: "Amanda felt her blood begin to boil. Amanda knew that would probably be bad. Actually, she was sure that would be bad. It had never happened to her before but... it just sounded bad."
