Today, I'm reading Anna Jarzab's Tandem (Many-Worlds #1). I was kindly sent an ARC by Random House back in August, and I'm absolutely loving this book so far.

Synopsis (via Goodreads)
You. Your best friend. Every person you know.
Many worlds. Many lives--infinite possibilities.
Welcome to the multiverse.
Sixteen-year-old Sasha Lawson has only ever known one small, ordinary life. When she was young, she loved her grandfather's stories of parallel worlds inhabited by girls who looked like her but led totally different lives. Sasha never believed such worlds were real--until now, when she finds herself thrust into one against her will.
To prevent imminent war, Sasha must slip into the life of an alternate version of herself, a princess who has vanished on the eve of her arranged marriage. If Sasha succeeds in fooling everyone, she will be returned home; if she fails, she'll be trapped in another girl's life forever. As time runs out, Sasha finds herself torn between two worlds, two lives, and two young men vying for her love--one who knows her secret, and one who thinks she's someone she's not.
The first book in the Many-Worlds Trilogy, Tandem is a riveting saga of love and betrayal set in parallel universes in which nothing--and no one--is what it seems.
