Neverwhere by Neil Gaiman.
A while back I started a list of books I definitely wanted to read this year, and Neil Gaiman's work was at the top of that list. I figured, he writes science fiction/fantasy a genre I can really get behind. Especially since there's no new Harry Potter to look forward to, unless JK's new book is book 8 (dear goodness, please let that be true!!), I figure that going back to older books is a fine plan.
Neverwhere was the first Neil Gaiman book I ever read. It was set in London, which won me over immediately. I have a thing for England and anywhere in England.
