I'm a fantasy fan. High fantasy, low fantasy, urban fantasy, you name it, and even better if it manages a dose of humour as well. My favourite author list is a mile long, but Marion Zimmer Bradley tops it easily, with Terry Pratchett, Jim Butcher, Yasmine Galenorn, Neil Gaiman and Guy Gavriel Kay as runners-up.
I read pretty much anything, including those 'stuffy' classics and a lot of children's and YA literature (I've been collecting World Book Day titles for years), but favourites are favourites. Interestingly, most of the children's authors I enjoy are British, while adult ones come from across the pond, including a strong Canadian contingent.
