Chance Hastings is alone. The person he was closest to was ripped away from him and sent to the world below the high city. Chance is determined to find his sister, no matter what it takes.

Zephania Aroson is being hunted by his own race for believing their leaders were wrong. The more he saw of the people of Earth, the more he realised they needed to be afforded the opportunity to live. He wasn't willing to stand by and watch the extinction of an entire race because his leaders commanded him to do so.

By saving the life of the human, Zephania finds his mate in Chance Hastings. Together they learn of a legend surrounding Chance and his siblings. With the help of a group of freedomers, Zephania and Chance begin the search for them. Along the way, they save Zephania's own family, and a new legend is uncovered.
