First of all, I love the title! The title and the cover drew my eye, and the back cover copy convinced me to buy the book. Now that's what I call marketing!
Ack-Ack is a character for the ages. Yes, he’s an intelligent, gun-wielding, talking monkey. When we first encounter him, he's a character in a video game, an online multiplayer adventure involving aerial combat of the WWII variety against German ninjas. Yes. Because 1) video games, and 2) this is an alternate world in which Germany and France merged into a single empire, so some history is different. Large nuclear-powered zeppelins fly the skies. If pressed to describe the setting, I’d call it “dieselpunk,” though, while I have heard the term, I’m not sure if I’m applying it correctly.
Needless to say, Ack-Ack turns out to be more than just a video game character. The other main characters--from the first book at least--are Victoria, former journalist investigating the death of her ex-husband, and Merovech, teenager and heir to the British throne. The death of Victoria’s ex is just the tip of the iceberg, and the three soon find themselves caught up a high-reaching plot, with nothing less than the future of humanity at stake … And that's just the first book in the trilogy. The stakes get considerably higher in the next two books.
This was every bit as much fun as I’d hoped. The action moves along at a brisk pace. The characters are fun. Ack-Ack himself is sensational. The SF concepts are properly mind-blowing. Some concepts--downloadable personalities and cyborg enhancements, for instance--are classic stuff, but Powell also includes nods to recent stories about whether or not we live in a simulated reaity and multiple universes and more. He’s not quite in Warren Ellis or Charles Stross territory as far as gonzo futurism goes, but he definitely approaches that level.
The ending of the third book seemed a little rushed to me. It just felt not quite satisfying, though I have a hard time putting my finger on exactly why. The Coda, “The Last Macaque,“ makes for a much better ending--or at least I think so--and I’m glad that it was included in this omnibus edition. The final short story doesn't really fit into the continuity of the rest of the book, but it's excellent, and a fun look at what amounts to an early draft of the titular Macaque.
I agonized on whether this was a four or five star book. It's one of the best SF novels I’ve read in a long time, and I definitely commend it to the attention of anyone with any interest in the genre. But it's also just not quite as Oh! My! God! amazing as some of the books I’ve rated at five stars in the past. In the end, I settled for four, but know that it's actually at least 4.5 if not higher. Highly recommended!
