The Princess and the Sorceress — Jaclyn Weist

When Genevieve was sent to the future, she didn't think she'd be able to fit in. A year later, she has great friends and the chance to go to college -- something that wouldn't have been possible in her own time. Jenny is just getting the hang of being a princess and can't wait for her wedding day. What she doesn't expect is a visit from Maurelle, an evil fairy bent on destroying everything Jenny holds dear. When Jenny and Genevieve are switched for a second time, they are thrown back into worlds they never thought they'd see again. If they're unable to stop Maurelle in her quest for revenge, they will be forever cursed to remain in a time not their own.
