Bring me the head of Ivy Pocket

"With the Clock Diamond in hand, she hurries to rescue her best friend, Rebecca, who is being held prisoner in a parallel world. But Ivy Pocket has fallen ill, there's a man in a white suit following her everywhere, and the Butterfields seem to be behind yet another plot to lock her away. With a few tricks and all the natural instincts of a master of disguise, Ivy Pocket is sure she can dodge her enemies long enough to pull off the most daring rescue anyone has ever seen."--Amazon.
