A brilliant neuroscientist who runs a black-market clinic extracting and selling human memories as immersive experiences accidentally acquires a memory containing evidence of an unsolved murder—and the original owner is willing to kill to get it back.

Dr. Clara Foyle was once a rising star in cognitive neuroscience, pioneering a technology meant to cure PTSD by isolating and extracting traumatic memories. When her funding was pulled due to ethical concerns, she took her tech underground. Now, she operates as a "Memory Broker," extracting cherished, thrilling, or forbidden memories from those willing to sell, and brokering them to wealthy clients addicted to experiencing other people's lives.
