What struck me about this novel is how it had such a distinct writing style and that the less you knew about it, the more exciting the book was to read. One of those books that gets passed around saying "just read this, trust me". It worked out well in this case.

The other book like that I enjoyed even more is qntm's "There Is No Antimemetics Division". It's one of the best complete works to come out of the SCP Foundation, a collaborative writing project. I won't say anything more other than "you should read this" unless you need some convincing. (There's a new video adaptation on Youtube that's fairly well done but it works much better as a book.)
