This small format hardcover (almost as small as a paperback) contains two novellas: Diamond Dogs and Turquoise Days. Both are set in the Revelation Space universe. Diamond Dogs is much less epic than his novels, being more of an idea piece. Although Reynolds’ prose is tight and elegant as ever, some of the passages seem just a bit too stilted. I think the short length of each novella (only about 110 pages) may be cramping the author’s distinctive style.
Even so, Reynold’s universe is still a very cold, enigmatic and frightening place which cares not a jot for humanity. I expected him to solve the riddle of Diamond Dogs, but Reynolds has chosen to let the artifact therein serve a more sinister purpose. Very elegant and more than a little spooky. Turquoise Days is more of a vehicle to give interesting tidbits of information on the Pattern Jugglers (an alien life form). Although the main character is engaging, and the story well rounded, Diamond Dogs is definitely stronger the stronger of the two.
