This is Crigger’s fourth book about Boothenay Irons, time tripping gunsmith. The book takes its name not from a gun but from an Appaloosa horse named Six Shot.
This time a LeMat pistol with a bloody past sends her back to the 1870’s. She and her fiance, Caleb, will be trapped there if they cannot find a way to stop an ancient curse. Boothenay and Caleb soon find themselves in deep trouble. She has to deal with a dangerous and sexually predatory sheriff. Caleb is captured by Nez Perce war leader Axe and faces death by torture. Boothenay with only her wits, Six Shot, and the trusty LeMat must attempt a rescue. Much violence ensues. Though this story is fairly short as novels go nowadays, it is quite enjoyable. (I do hope this isn’t Crigger’s final gunsmith book.)
