I aimed to do a bit more reading this year and managed to make it to 50 books, this probably doesn't seem much to some people, but I read quite slowly and only tend to read during my work lunch break. Of those 50 though all of them are new not re-reads. 

Very few of the books on the list are 'new' for 2005 (5 in fact) although there's a couple more that were new in paperback.

Best Book I read this year - Without hesitation this one is The Sparrow by Mary Doria Russel, it's an amazing collection of character studies that was simultaneously horribly painful to read and completely compelling.
Honorable Mentions - Orson Scott Card: Ender's Game, Banks: The Wasp Factory, Susanna Clarke: Jonathan Strange and Mr Norrell, Clifford D Simak: City
Most enjoyable book of the year - Jack McDevitt: Chindi, Niven and Pournell: The Mote in God's Eye, Joanne Harris: Chocolate, Dan Simmons: Olympos, Connie Willis: To Say Nothing of the Dog
Disappointment of the year - Harry Potter 6 was an enjoyable read but the lack of plot and abundance of cliche was a disappointment, the lack of a new Dalziel and Pascoe was annoying.
Can someone explain the fuss about - Cloud Atlas by David Mitchell - it was ok but I just felt it was an interesting concept not really done justice by mediocre story telling
Struggle to finish - Strange and Norrell: a great book but boy was it slow going
Worst book - Mobius Dick by Andrew Crumey - pretentious and irritating

Best non-fiction - I've read 7 non-fiction books this year and most of them have been pretty poor. The standout was Sophie's World by Jostein Gaarder which probably only really 1/2 counts as non-fiction. It's a beautifully structured book that introduces the history of philosophy through examples both obvious and hidden. It's hard going at times, but definately worth reading.
Worst non-fiction - A toss up between Simon Winchester's Map that Changed the World (cheesy and hackish) and Francis Spufford's The Child that Books Built (clumsy autobiography littered with pop-psychology and waffle)
