The Fractal Prince (Jean le Flambeur)

Blurb

"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 The Fractal Prince, 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.
