In the third installment of Mark S. Roberts' The Clio Project series, Technical Sergeant Scott Rees and his team are caught between scientific advancement and a power struggle over the Clio time machine in their attempt to right what has become an altered historical timeline. The modern fighters have progressed from unwitting participants to active contributors in a top-secret time travel experiment. Now, they must navigate multiple potential historical outcomes while extricating themselves from the challenges of a return visit to the Civil War. Confederate Rebels have taken a keen interest in modern equipment that must not remain in the past for fear of turning the tide. Losing men in the process is a necessary risk, but one Rees and his team must take to protect the future and present-day reality as they know it.
