I have a strong memory of seeing this book on the shelf around the time I first started working at my library. It was probably on the new fiction shelf, though I could be mistaken. I was reminded of this when I encountered the book at a used book store recently. But despite my memory of seeing the book, I couldn't recall if I had actually read it, though the illustrations were so familiar. So I read it again. Throughout the story, I never really knew what was coming next. But at the same time, everything felt strangely familiar. I suspect that I did read this book years ago, but forgot it because it is so lackluster.
In the introduction, the author reveals how the book started as a private project of him painting a setting starting from the image of a flying saucer and sailing ships and it was only later that he came up with a story to link it together. This is almost painfully obvious at times. There are important details mentioned in the story that are never illustrated, like some vague symbol that suggestively shows up in different places, including an important crystal worn by a main character, yet which is never shown in illustrations of that character; or the fact that the main villain is wearing the mummified severed hand of one of the main characters, but again this is never shown. And in many places the art appears to be concept sketches just thrown in wherever. Late in the book there is a picture of a robot riding a horse with the caption "Another time, another place" and absolutely no mention in the text, and of no relevance to the plot.
Despite my complaints about the art so far, it is actually the one good point of this book. The art really is quite well done and frequently has a spark of real potential. But the story they are attached to is really dull, poorly plotted, and full of uninteresting characters. The revelation that the robots really have biological brains is incredibly stupid, and provides no real explanation, especially since the organic component is apparently a microorganism; how does have something like mold growing in the computer brain of a robot explain anything about their self-awareness? It is lazy hand-waving, an appeal to knee-jerk dualism misplaced onto the idea that there is "something special" about biological life. And though the main villain is quite evil, and you could even say that their own actions bring about their downfall, it is sort of twisted that everything they worried about seems to come true at the end. Caps is effectively immortal, superhuman, and set up with a new young girlfriend. Can't help but sense at least a whiff of misogyny in how that aspect of the story works out.
