Caiden has been on the run for ten years with his unique starship in order to keep his adversary, Threi, imprisoned. But when an old friend he'd once thought dead reappears, he is lured into a game of cat and mouse with the one person whose powers rival Threi's: Threi's sister Abriss.

Now with both siblings on the hunt for Caiden and his ship, Caiden must rescue his long-lost friend from their clutches and uncover the source of both his ship's power and his own origins in order to stop Abriss's plan to collapse the multiverse.
