In this riveting historical horror novel, Frankenstein is vividly reimagined in the Wild West. With equal parts Cormac McCarthy, Mary Shelley, and Stephen Graham Jones, Rountree deftly navigates the terrible aftermath of love and death. “What begins as The Searchers meets Frankenstein ends as Unforgiven meets The Magicians . A dark, brooding meditation on both what we’ll do for love, and the callous indifference of the hardened souls of the early West.” ―C. Robert Cargill, co-screenwriter of The Black Phone Catherine Coldbridge is a complicated woman: A doctor, an occultist, and, briefly, a widow. In 1879, Private Frank Humble, Catherine's husband, was killed in a Sioux attack. Consumed by grief, she used her formidable skills to resurrect him. But Frank lost his soul after the reanimation, and disappeared after a killing spree. Unable to face her failure and its murderous consequences, Catherine fled to grieve. Twenty-five years later, Catherine has decided she must make things right. She travels back to Texas with a pair of hired killers ready to destroy Frank. But Frank has remade himself as the Unkillable Frank Lightning, traveling with the Wild West Show. Reaching for a last chance at redemption, Frank and Catherine are at an impasse. As time runs out, their final choices may result in considerable bloodshed.

S. Humble, author of the That Light Sublime trilogy “In 1879, less than two weeks after his wedding, Private Frank Humble is killed while on patrol along the American frontier. Unwilling to accept his death, Dr. Catherine Coldbridge draws on her magical powers to resurrect her beloved husband. Expecting a miracle, Catherine is horrified when Frank returns not as the loving man she remembered but as a bloodthirsty monster. Decades later, Catherine tracks him to a touring show called ‘Cowboy Dan’s Wild West Revue,’ where he is billed as the Unkillable Frank Lightning. Along with a pair of sharpshooting brothers, Catherine is prepared to finally right the wrong she committed until she realizes Frank is not as monstrous as he originally appeared.
