Being an expert in information searches, image processing and enhancement, pattern matching, and data forensics earned Jason Wood a lot of money – from private contracts and working with the police. And it was a nice, comfortable job most of the time. But then an informant showed up dead on his doorstep, a photograph didn't show someone who'd been in the viewfinder when the picture was taken, and Jason's world is suddenly turned upside‑down. Against things that violate the very reality he thought he understood, Jason has only three weapons: his best friend Sylvie, his talent for seeing patterns… and his ability to think beyond the pattern and see a solution that no one else imagined. Against the darkness of the unknown, the greatest weapon is the light of reason. A vastly expanded and revised edition of Digital Knight, Ryk E. Spoor's first published novel, Paradigms Lost adds two brand new adventures for Jason and includes many chapters of additional material within the originals.
