When Harley Axelson finds herself falling into another dimension through her closet door mirror-into a dimension of people with wings, monsters of ice and blue flame, and the cheery "alter ego" Afton-everything she knows about the world is thrown out the window. Inter-dimensional travel is real. There are infinite parallel universes with Harleys under different names, with friends and family with personalities eerily similar and drastically different. And mirrors are the portals, only open to those who contain the ability to fall through them: Transversals. So reveals Harley's chance to escape from her mediocre-at-best life with newly acquired friends on the other side of her mirror. But the dangers of traveling are costly and the stakes run higher the more she does, the more she learns about her past, herself, and the universe around her. Not to mention flaming ice monsters are following her through dimensions, a technologically advanced one nearby is turning corrupt, and her safety in the two dimensions she holds dear are making Harley question her true place among them.
