Rook by Blaine C. Readler

In Rook by Blaine Readler, the titular character is swept from life as a primitive tribesmen into an interstellar adventure through time and space, encountering legendary figures and changing the course of history. The plot is ambitious and fast-moving, boasting educational moments and light-hearted scenes. The underlying reason why Rook has been chosen as a time-traveling liaison to an alien race isn’t entirely clear, but Readler has written a fascinating journey for him to take. Going from the formation of Roman empires to the assassination of Abraham Lincoln, Rook is an unpredictable, tongue-in-cheek ride through human history, with plenty of meaningful lessons scattered along the way.
