Facing relentless enemies, harrowing trials of life and death, and an unyielding fate, he’s forced to confront the ultimate question: how far is he willing to go to protect the people he loves?Filled with emotional struggles, determination, unexpected humor, and a touch of romance, this story asks a powerful question to the readers: What would you sacrifice for the people you love?

One week. If you survive, you choose a Cosmic Power... you survive. Jace isn’t one to give up. Not when his sister dies. Not when he loses his legs. And definitely not when The Cosmic System takes over Earth. With nothing more than his street smarts, the clothes on his back, and a river otter companion; he must survive a planet full of vicious predators that see him as an easy meal. If he can survive? He gets to choose a Cosmic Power and a Class. A path to ascension. A way to bring his sister back.
