1866. Dakota Territory. Red Cloud's coalition of tribes battles the U.S. Army to reclaim its hunting grounds in the Powder River Valley. Against this background, Wolves of Eden sets four men on a deadly collision course in a narrative that explores the cruelty of warfare, the power of love, and the resilience of the human spirit: Lieutenant Martin Molloy and his loyal orderly, sent West to investigate a triple murder at a frontier fort; and Irish immigrant brothers Thomas and Michael O'Driscoll, who survive the brutal front lines of the Civil War only to find themselves as both hunters and the hunted in another bloody campaign.

Blending intimate historical detail and emotional acuity, Wolves of Eden firmly establishes Kevin McCarthy "in the companyof masters like Patrick O'Brian and Hilary Mantel" (Stephen Harrigan).
