Together with her twin brother Charlie, an identical Charlie from a parallel Earth, mysterious Eve, enchanting Ben, and unconventional but endearing scientist Dr. Waldo, can Emma chase down Vik, a man under the influence of an entity called The Void, before he destroys all the universes?"--Amazon.com.
