Zombies versus cavemen: Gash-Eye already thought life was hard as the Neanderthal slave to a band of Cro-Magnons. Then zombies attacked, wiping out nearly everyone she knows and separating her from the Jaw, her half-breed son. Now she fights to keep the last remnants of her former captors alive. Meanwhile, the Jaw and his father try to survive as they maneuver the zombie-infested landscape alongside time travelers from 30,000 years in the future.
Part H. P. Lovecraft and part Alien, Ironheart is the story of what happens when the mining ship Canary comes across a strange derelict on the edge of the galaxy - a derelict occupied by a strange woman, a woman who cannot possibly exist but does.
