Shadow Ender (Hardcover) (ISBN-13: 9798992873689)

Callie's Light Cores are gone. She's imprisoned in a desert world. Her Seer Toran blames her for the death of his sister. Oh, and the Queen Beyond the Stars is one step closer to destroying the multiverse.

So, things are just great.

Callie must find the remaining Light Cores before the Queen's evil Shadowmancer minions do. But this world's Light Core is hidden at the center of a homicidal death maze that only a Luminaut can conquer. Figures, right?

To make things more fun, formerly evil, mostly undead (and still smoking hot) Nate Ormandi arrives to help Callie and her friends. And he's got Toran's very much alive sister with him. Surprise!

However, as Nate and Callie work to conquer the death maze, Toran keeps leading them into traps. Is Callie's grumpy Seer trying to get them killed, or is someone else pulling the strings?

Time is running out. The Darkness is stronger than ever. As the line between enemy and ally blurs, the last Luminaut will face a terrible choice, one that will change the whole multiverse forever.
