New York Times best-selling authors S.M. Stirling, Mercedes Lackey, Eric Flint, and Jody Lynn Nye return with four novellas. The cat-like Mrem, our heroes, battle the deep reptilian intelligence of humanoid dinosaurs in a Bronze Age world. After the extinction asteroid does notstrike Earth, the dinosaurs keep evolving–but so do the mammals. We mammals have achieved humanlike shapes, but now it’s cold‑blooded, magic‑using reptiles against the hot‑blooded, hot‑tempered descendants of cats.
