October 1, 1890. Colonel Annika Wise is stranded in time. After Kyle Mason and Padma Mahajan return to the year 2008, Annika is stuck in 1890 Deadwood, unable to escape. After the punishing defeat of the U.S. Army at the Massacre of Grand River, the military will stop at nothing to exact revenge on Annika and her Lakota allies. After Annika foretells the destruction of San Francisco in 1906, she is labeled a "witch" by W.R. Hearst and Teddy Roosevelt's administration. Targeted for capture by Pinkerton agents, Annika seems doomed until a mysterious agent from the mid-century intervenes. Together, Annika and the agent leverage their knowledge of the future to change the course of human history, until Kyle Mason is ordered to return to the past to stop Annika by any means necessary.
