One of the touchstone books of my adolescence. I read it at about 13, I suppose, and was utterly enthralled. Rereading now doesn't quite give the same experience, of course (it's easier to see the flaws, for one) and if I'd just read it for the first time (instead of the fifteenth, probably) I'd probably give it four stars, but my remembered love for this book pushes it up to five.

It reads like fantasy but the sequels do place it a bit more in science fiction, I suppose. Anyway, this was the best of the three books in the trilogy, and I particularly liked how the text made very clear that the main character's fascination with the vamp was grossly ill-advised.

I think my favourite part of it, that kept me going back, was the setting. On an engineered, terraformed Moon, with the Earth hanging heavy in the sky and filled with genetically engineered creatures and the remnants of old technology... it was just wonderful.
