Sundance 13: Blood on the Prairie

Half English, half-Cheyenne Indian, Sundance was a half-breed who took on jobs no one else would handle, a killer who never missed. And he charged plenty for his services. But when his old friend George Crook asked Sundance to step into the most explosive situation of his career, as a personal favor, Sundance agreed. He was the only man alive who could keep the Sioux nation from going on the warpath—and Russia from going to war with America.
Sundance was the best … but just maybe this time out the job was too much even for him!
