Wow, thanks for the onslaught of responses chaps / chapettes
I have read through the Harry Potter books and His Dark Materials, enjoying both thoroughly. The list you provided Dogma was excellent and contained the 'mainstream and popular' books I was after, although in such a bit list it's slightly intimidating! Could you perhaps recommend a select few out those you have provided?
Your wish is my command

These are some of the few I've read and throughly enjoyed. Most of these books are kids books but I still think they should be read. I also find a lot of the "classics" a bit of hard going and that's not what you're looking for. You also have to remember, just because a book/author is popular doesn't mean you'll enjoy reading them.
4. The Hitchhiker's Guide to the Galaxy, Douglas Adams
9. The Lion, the Witch and the Wardrobe, CS Lewis
35. Charlie And The Chocolate Factory, Roald Dahl
42. Watership Down, Richard Adams
46. Animal Farm, George Orwell
56. The BFG, Roald Dahl
62. Memoirs Of A Geisha, Arthur Golden
74. Matilda, Roald Dahl
81. The Twits, Roald Dahl
Everybody should read Roald Dahl, yes they are kids books but they are amazing! The Twits was one the first books I ever read.
Memoirs of a Geisha is a very good, powerful book. And if you ever get round to reading and enjoying it another author along the same vein who I would suggest would be Anchee Min.
I would also recommend The Girl with the Dragon Tattoo (and sequels) by Steig Larsson, and of Simon Kernick and Lee Child's books also.
Simon Rothfuss has a book that reminds me of the Lost Odyssey memories, if you like that sort of thing too.
Also, Trudi Canavan has got 2 series out Age of Five and The Black Magician and they're well worth a read too.
I read a lot but I tend to just go into a bookshops and look at the spines of books, if I see one I like I pick it up and read the blurb. It's how I discover a fair few authors that I normally wouldn't read.
Sorry I get carried away when it comes to books!!
