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.

Now to have a fighting chance against the most influential siblings in the multiverse, Caiden is left with no choice. He must unlock the Azura's true potential--which means finally confronting his own mysterious genetic origins.

"Unpredictable and strikingly unique, Azura Ghost is science fiction without any limits to its imagination. Genre-breaking brilliance!"--David Dalglish, USA Today bestselling author

"A blistering crash through bubble universes, seas of the luminous dead, and sleeping alien cities. Liquid-crystal star ships, living machines, reality-cleaving swordplay, and a dynasty whose words command your synapses and cells. Heart-heavy, astonishingly inventive, with language that burns like plasma. A biomechanical sucker punch of a book. The space opera you've been waiting for."--Micah Dean Hicks, author of Break the Bodies, Haunt the Bones

"Essa Hansen is one of the most imaginative authors in science fiction today, and in AZURA GHOST she delivers a thrill ride of a story."--Michale Mammay, author of Planetside

"Azura Ghost is a magnificent achievement. Hansen juggles multiple universes as if they were fireballs, without ever dropping a single one. Like the best of science fiction, Azura Ghost asks the questions that we often fear to ask ourselves: about the extent of our responsibility in this world, what it means to choose, the limits of empathy, and the inevitability of loss; and like the best of science fiction, it asks them both at the scale of the cosmos, and at the level of a single human heart. The novel's ambition is upheld by soaring prose, which does full justice to the scope of Hansen's imagination. An instant classic." -- Gautam Bhatia, co-ordinating editor of Strange Horizons and author of The Wall and The Horizon
