Born of two dragons but raised in a lab, Ruby has lived a life of quiet regulation, waiting until the project proposed decades earlier can be started. When Dimensional Arrest, Retrieval and Extraction gets underway, her innate ability to jump dimensions puts her on the front lines with her sisters, retrieving people from earth whose presence is tearing their home world apart. Each assignment takes Ruby to another world to retrieve scholars, criminals, researchers, and escapees. The freedom she feels on the new worlds is cruelly taken away when she has to return to earth over and over again. Meeting one of her own kind is a shock, but his determination to help her gain her freedom is even more of a stunning revelation. He offers her a life without walls, in the sun, and wind in her hair. What dragon could resist?
