Rose is a post-recession, struggling graduate, who is suddenly taken into a mirrored, shadowy world, where she learns she is the new queen of Iudex. She is rescued by the king of Ignusia, who she later discovers to be the boy who disappeared from their world ten years prior—Declan. With the fate of the kingdom lying in her hands, she must learn fast while avoiding the entanglements of war, escape, and love.
