In the multiverses, everyone has multiple versions of themselves. These versions are called analogs. Sasha Lawson, Earth, knows nothing about analogs, but she does know that she's thrilled when hottie Grant asks her to prom. She doesn't know that Grant is actually Thomas, Grant's analog from a different universe that needs Sasha because she is the analog to their princess. When Thomas takes her back to his universe, Sasha will have to pretend to be the princess if she ever wants to go home and has to hope she won't die along the way.

For me, TANDEM has a slow start. Sasha is very much the stereotypical teen girl, eager to go to prom and blush-y around her crush. However, once she gets into Thomas's universe, the story goes so fast that my fingers had a hard time keeping up. Also, the need for Sasha to act like a stereotypical teen girl proves to be a great set up for character development later on, and it's a clever reflection on how normal her life was before. Thankfully, that first part isn't too long.

The concept behind this story might mess with your head a little bit, as often dimensional/multiverse stories do, but the explanations throughout the story are impressive and very helpful. The plot is layered nicely because of that, and it sets it up well for potential future books.

The relationship between Sasha and Thomas is full of swoons, heartache, and several frustrating moments. The ending packs a punch, and I hope that there will be a sequel. In between Sasha's story, author Anna Jarzab puts in pieces of the princess's story that Sasha is impersonating. The glimpses are more for plot set-up, but I love the look into the princess's situation. I would have liked more of those, but the main focus of the story is clearly on Sasha.

If you enjoy books by authors like Myra McEntire or shows like Doctor Who, TANDEM by Anna Jarzab is definitely a good book to read, and I will be highly anticipating a second!
