Azura Ghost

One man and his sentient starship are all that stand between the multiverse and its total destruction in the second book of Essa Hansen's brilliant, mind-bending space opera trilogy. Caiden has been on the run for ten years in order to keep his Graven ship out of the hands of his old adversary, Threi. But when a childhood friend he once thought dead reappears to take it, he is lured into a game of hunter and hunted with the one person whose powers rival Threi's: his sister, Abriss.
