"Epic, humane western of the settlement of Oklahoma and Jesse James’s missing gold...Callen’s storytelling is brisk and lively, attuned to the complexities of history—of the James and Dalton Gangs, of the Sooners and the Boomers, of the politics of westward expansion...but it’s the sweep of history and the lives caught up in it that gives The Unassigned Lands life." - Booklife
