The Quantum Thief (Jean le Flambeur Book 1)

Jean le Flambeur is a post-human criminal, mind burglar, confidence artist, and trickster whose origins remain mysterious. His crimes are known throughout the Heterarchy, from breaking into the vast Zeusbrains of the Inner System to stealing rare Earth antiques from Mars's aristocrats. Imprisoned in the Dilemma Prison, where he must kill himself each day before his other self can, Jean is rescued by the mysterious Mieli and her spacecraft. She takes him to the Oubliette, the Moving City of Mars, where time serves as currency, memories are treasures, and a moon-turned singularity illuminates the night. Mieli offers Jean a chance to regain his freedom and his former powers in exchange for completing a heist he never finished. As Jean carries out a series of capers for Mieli and her mysterious masters, investigator Isidore Beautrelet is called to investigate a chocolatier's murder. His investigation leads him to the trail of an arch-criminal: le Flambeur himself. Set several centuries in the future across the solar system, this debut novel combines elaborate worldbuilding with human motives of betrayal, revenge, and jealousy.
