The Quantum Thief
In a future where memories can be extracted, stored, and traded like currency, the most valuable thief in the world is one who can steal memories you did not even know you had. Ren makes a living lifting forgotten memories from the wealthy — childhood traumas, embarrassing secrets, inconvenient truths that people pay to have removed. But when a mysterious client hires her to steal a memory from the Prime Minister himself, Ren discovers a secret that someone is willing to kill to protect. The memory leads her to a underground network of people who have all had the same memory stolen from them: a memory of a city that does not exist on any map, a city of silver towers and impossible architecture. As Ren pieces together the fragments, she realizes the city is real, it is hidden, and the people who built it do not want to be found. And now they know she is looking.

✎ Editor's Review
Hiroshi Sato blends cyberpunk and noir in this sleek, stylish thriller. The memory-as-currency concept is handled with sophistication, and the mystery unfolds at a perfect pace. Ren is a compellingly flawed protagonist — talented but haunted by gaps in her own memory. The silver city mystery is genuinely uncanny. Some readers may find the world-building dense, but those who enjoy immersive sci-fi will find much to love here.
