Tandem by Anna Jarzab

Tandem (Many-World, #1) - Anna Jarzab

Parallel universes collide in the first book of this original fantasy series. Sasha cannot believe it when the guy she has crushed on from afar, Grant, starts talking to her and eventually asks her to prom. Unfortunately, Grant is not who he says he is, and it is too good to be true. After prom, Sasha wakes up a prisoner, in the parallel universe of Aurora, where her “analog” (replica) in this universe is a princess, who is missing. The General offers her a deal- pretend to be Princess Juliana for the next six days and they will send her home. But what he doesn’t know is that Sasha has had dreams of being Princess Juliana most of her life, and she may be able to find Juliana and figure out what is going on. She just needs to figure out if her guard Thomas (Grant’s analog), who has already lied in order to get her here is trustworthy and willing to help her. 
This book was creative and fascinating. Parallel universes, analogs, politics, war, insurgents and the upcoming arranged marriage for the princess, surround this novel with mystery, intrigue, romance and excitement.
