I just finished Charles Gannon’s Marque of Caine. It’s a wild ride through alternate universes and star systems controlled by a variety of aliens. The protagonist, Caine Riordan, is an intelligence specialist and “jack-of-all-trades,” looking for the love of his life, who is in the hands of aliens whose intentions are at best uncertain. He’s persistent, sometimes has to blunder through, but usually gets things right despite being surrounded by unfamiliar social mores and advanced technologies. I especially enjoyed his descent into Britain during an alternate 19th century with echoes of London Bridge Coming Down. Despite the epic in which he lives, Riordan is an effectively drawn character.
