About the book: 2022 / Eurocon, Wandering Star, Galaxy Awards. Nominations for the Locus Award, John Campbell Memorial Award. Best SF -Book of the Year by Kirkus Review and Library Journal. Jean le Flambert is a post-human and a criminal, a mind hacker, a self-confident trickster. His origins are shrouded in mystery, but his exploits are known throughout the solar system. Rescued from a futuristic prison by the mysterious Mieli and her sentient spaceship, Jean travels to Mars, the Moving City, where time is currency, memories are treasure, and the moon-turned singularity illuminates night. Mieli has given him the chance to regain his freedom and the power of his former self - in exchange for completing a heist he once failed. They are on a wild ride through the solar system of the future, a world of ubiquitous cryptography, memory sharing, and a race of superhumans that have emerged from MMORPG guilds. Despite all its wonders, this world is still ruled by human motives - betrayal, revenge and jealousy. "Inventive, exotic, with complex, intelligent intrigue." — The Times "It's hard to admit, but I think Ryaniemi understands hard science fiction better than I do." — Charles Stross “Many authors would kill to write prose half as good as this…” — The Financial Times “Holding narratives and characters… SF concepts are terribly good.” — Sci-Fi Now “Fountain of Ideas.” — Interzone “The Quantum Thief, like the other best space operas of this century, is a house of wonders, where the propositions instantly become tradition and the arguments catch the eye.” — John Clute “A brilliant novel!” —Strange Horizins
