Time Skipper, Eli Skiwen, Book 1

This is a book about a girl who finds the power to skip through time. But, she can't go to any certain time whenever she wants. It's completely random. Then she meets a boy named Darlen Sharer, who has the power to control time, but can't travel through it. Only with each other's help can they go to the necessary places to stop the evil time lord, Erenave. With Eli's trusty monkey, Markers, and suitcase of disguises, the three of them embark on a quest of a lifetime.
