@Ericcq: I love Pullman and agree on Brown - OK for one read, but that's it and two of them were enough. He writes lousy characters. Pullman of course is wonderful

My favourites? Many...
author:
Jonathan Carroll, hands down
He has been classified as a fantasy writer, even as horror I guess and probably other genres, but none of that really hits it. If you ask him, he refers to his writing as "magic realism",but it is totally different from the South America branch.
Anyway, his books have a quality of drawing me in from the first line and spitting me out in a trance like state in the end. He creates characters that talk to me and stories that often start very usual, but then slowly drift off into the fantastic and before you know it you turn around and nothing in the world he describes is famliar any more. Yet he writes it in a way that I can believe every word is true and imagine all this could happen. With some books he throws me right into this world, with some, he only touche on it and integrates the fantasy elements so seamlessly that anything seems possible.
He also creates great characters, especially interesting women and I generally enjoy his writing style. He has an awesome blog as well. The little things he posts there are just wonderful.
favourite books by him?
The Marriage of Sticks and
Bones of the MoonBooks, in no particular order:
Reinhold Ziegler: Es gibt hier nur 2 Richtungen, MisterA book I have loved in my youth and still enjoy reading. It's about a man who sets out for a travel across the US to find luck, to find himself, to figure out where and who he wants to be. It's a wonderful and interesting journey that is fun to read. It also gives an interesting look at the US.
Most of all though, the thoughts he shares on his journey touch me deeply. It also includes one of my favorite quotes: Träumer? Wir sind alle Träumer. Wir schlucken es nur zu tief runter, weil wir immer wieder gesagt bekommen, daß man im wirklichen Leben nicht träumen darf. (Dreamer? Each one of us is a dreamer. We just push it down deep because we are repeatedly told that we are not allowed to dream in real life."
Mary Lawson: Crow LakeAgain, the story touched me deeply. It's about families and missed chances and how one's own values do not have to be everyone else's. It is very well written, but the main reason I enjoyed it so much was that it reminded me of my own family - totally different story there, but some of the feelings were eerily similar.
Michael Ende: Der Spiegel im Spiegel (Mitrror in the Mirror)At first glance, this is "just" a collection of short stories, but after a closer look I noticed that they are all connected and the whole is so much more than the sum of its parts. Very well written, anything from scary to sad to funny and all simply wonerful. I need to re-read that one!
Audrey Niffeneger: The Time Traveller's WifeGreat story, great characters. Well told with flashbacks and changing perspectives. It had me hooked from the first page.
Khaled Hosseini: The Kite Runnersad, beautiful, brilliant! nuff said.
Anita Amirrezvani: The Blood of FlowersVery sensual writing. I could see, hear, taste and smell what she described. Great story too and a wonderful female main character who goes her own way in a time and place where that was virtually impossible for women. Loved it.
I don't want to bore you so I'll add more later...
