A
series of
books by
Tad Williams. Sort of
cyberpunk, but not in the
common vein (i.e.
William Gibson or
Neal Stephenson). It's about a group of strangers who are united by the fact that something has happened to a
child they know to put them into a
coma, and they suspect that it has something to do with a
massive virtual reality known as
Otherland. A bunch of these
people end up going to
explore the
virtual reality in the hopes of finding out what has happened to the
children.
Quite good, if slightly long-winded.
