Argonaut Affair (Time Wars)

Book 7 of Time Wars. Has just a little wear and looks very nice. When a centaur appears in the twenty-seventh century, Delaney, Cross, and Steiger, three time commandos, are sent back to ancient Greece to correct the timeline. The story involves the adventures of an organization tasked with protecting history from being changed by time travelers. In the world of the series, many people and events considered fictional are historical, and vice versa; the action of each book in the series weaves in and out of the events of a famous work of literature.
