I'm in the middle of Snow Crash and the new Thursday Next book.
I got bored with them both. Actually, I fell asleep in the middle of the former, and want to start reading it again at some point soon so I actually understand what's going on.
as for the latter, I just don't think I could be bothered finishing it.
others on my to read list include:
Chart Throb - Ben Elton
The Gulag Archipelago - Aleksandr Solzhenitsyn
The Dark Tourist - Dom Joly
The Left Hand of God - Paul Hoffman
