The Quantum Thief sequel is “stupefyingly entertaining, like a heist movie for post-singularity, AI-boosted string theoreticians from beyond spacetime” (Charles Stross). “The good thing is, no one will ever die again. The bad thing is, everyone will want to.” A physicist receives a mysterious paper. The ideas in it are far, far ahead of current thinking and quite, quite terrifying. In a city of “fast ones,” shadow players, and jinni, two sisters contemplate a revolution. And on the edges of reality a thief, helped by a sardonic ship, is trying to break into a Schrödinger box for his patron. In the box is his freedom. Or not. Jean de Flambeur is back. And he’s running out of time. In Hannu Rajaniemi’s sparkling follow-up to the critically acclaimed international sensation The Quantum Thief, he returns to his awe-inspiring vision of the universe . . . and we discover what the future held for Earth. “Stories within stories, mind-boggling scientific extrapolations, and flamboyant characters mark the author as a rising star of the genre.” —Library Journal “Rajaniemi’s witty language and charmingly wry hero will make the read well worth the effort for the first installment’s fans.” —Publishers Weekly “Fans of the author’s popular debut novel, which mixed hard science with wild fantasy, will probably be lining up for this follow-up, which resolves some of the questions posed in The Quantum Thief but, on the other hand, asks several more, for which there are, as yet, no answers.” —Booklist
