Solaris - the 60's Stanislav Lem sci-fi novel is well worth a read.

Solaris by Stanislav Lem.

Every Unix sysadmin should spend some time reading "real" books. In fact Martin Vermeer suggests there is a connection between Unix and literacy. So why not pick up the book from where the operating system got it's name (a search on google news could give me no proof of this - once I have some hard evidence I will provide it). Solaris is an excellent sci-fi/psychological read and was later filmed by Tarkovsky (and has now been remade by Stephen Soderbergh with George Clooney as Kelvin).
