The novel "Demon" is the last book in the trilogy that starts with "Titan" and continues with "Wizard". "Titan" starts off in an interesting way with a space ship crew ending up on giant alien space wheel in orbit around Saturn. The description of the personalities start off in a very crude way in Titan, but slowly improves. The end of Titan made me hope for some interesting continuation in Wizard, but I was disappointed. Most off the stuff in Wizard didn't make much sense, and it's not only because most of the crew apparently went mad, and the wheel is controlled by a mad entity. It seems the author just filled in with whatever stuff came into hs mind as he went along, without checking if the overall story was making any sense. For example, no scientists seemed to have any interest at all in the wheel, they just left it alone for tourists to fool around in. Then some random magic is thrown in for the heck of it. I'm not sure why I read all three, and didn't just stop somewhere before the last page. Possibly it's because I have an interest in how life might be in space stations. I'm not sure most people have such stamina, though. It's not a page-turner. It felt like an ardous task most of the time. Some of the sex in the trilogy is pretty good, though...
