Mercy Lynch, recently widowed and taxed to exhaustion by caring for Confederate wounded in Richmond, must cross the war-torn nation to reach her estranged father, who lies dying in the Washington territories.
After her dirigible is shot out of the air, Mercy joins Horatio Korman, a Texas Ranger with an agenda, on the Union’s famous steam engine, the Dreadnought. On their trail are desperate Confederate soldiers and a zombified Mexican legion.
The battles and intrigue are entertaining, but the real draw is Priest’s latest no-nonsense heroine, who comes equipped with a full measure of sharp judgment and brutal competence as well as a nurse’s kind (but not saintly) heart.
