Time Warp — Robin Buckallew

Volume 9 of the Leafy Tom Series. Young. Thin. Dances. This is the only description them men have of the girl with the power. It fits everyone in Phoebe's advanced dance class...but not Alba. So when two girls are missing, and one of them is Alba, there are about a million questions. The answers will send Anikka's team in several directions at once, and will pit them against one of the biggest, most difficult adversaries they have ever faced. But their opponents underestimated the witches. It never occurred to them that anyone would send more than a dozen witches to rescue one teenage girl...and, of course, a bear, a bat, two dogs, and a cat. And it all starts with one very unstable dance spell.
