The Cas Russell series (also known as Russell’s Attic in its original self-published editions) is S.L. Huang’s signature work. The premise is striking: Cas Russell can do complex mathematics instantaneously, allowing her to calculate bullet trajectories, structural weaknesses, and physics in real-time. This makes her an extremely effective mercenary.
The series includes full-length novels (Zero Sum Game, Null Set/Plastic Smile, Critical Point) plus shorter stories and novellas. The books were originally self-published before Tor picked them up, and the traditional publishing editions sometimes carry different titles from the self-published versions.
