Just another day in the Dilemma Prison. Rescued by the mysterious Mieli and her flirtatious spacecraft, Jean is taken to the Oubliette, the Moving City of Mars, where time is a currency, memories are treasures, and a moon-turned-singularity lights the night. Meanwhile, investigator Isidore Beautrelet, called in to investigate the murder of a chocolatier, finds himself on the trail of an arch-criminal, a man named le Flambeur...Indeed, in his many lives, the entity called Jean le Flambeur has been a thief, a confidence artist, a posthuman mind-burgler, and more. His origins are shrouded in mystery, but his deeds are known throughout the Heterarchy, from breaking into the vast Zeusbrains of the Inner System to stealing rare Earth antiques from the aristocrats of Mars. In his last exploit, he managed the supreme feat of hiding the truth about himself from the one person in the solar system hardest to hide from: himself. Now he has the chance to regain himself in all his power—in exchange for finishing the one heist he never quite managed.The Quantum Thief is a breathtaking joyride through the solar system several centuries hence, a world of marching cities, ubiquitous public-key encryption, people who communicate via shared memory, and a race of hyper-advanced humans who originated as an MMORPG guild. But for all its wonders, The Quantum Thief is also a story powered by very human motives of betrayal, jealousy, and revenge.

    . . through quantum space–time.  Minor Universe 31 is a vast story-space on the outskirts of fiction, where paradox fluctuates like the stock market, lonely sexbots beckon failed protagonists, and time travel is serious business. Every day, people get into time machines and try to do the one thing they should never do: change the past. That’s where Charles Yu, time travel technician—part counselor, part gadget repair man—steps in. He helps save people from themselves. Literally. When he’s not taking client calls or consoling his boss, Phil, who could really use an upgrade, Yu visits his mother (stuck in a one-hour cycle of time, she makes dinner over and over and over) and searches for his father, who invented time travel and then vanished. Accompanied by TAMMY, an operating system with low self-esteem, and Ed, a nonexistent but ontologically valid dog, Yu sets out, and back, and beyond, in order to find the one day where he and his father can meet in memory. He learns that the key may be found in a book he got from his future self. It’s called How to Live Safely in a Science Fictional Universe, and he’s the author. And somewhere inside it is the information that could help him—in fact it may even save his life.
