My favorite is probably fantasy. Big Lord of the Rings fan. I feel at home in a very specific niche, namely 'the historical + high fantasy epic tales genre.' What I dislike is science fiction. All of it, all of it! I think I lean toward mystery, thriller type stuff, but also enjoy romances (especially the historical ones...which are not at all historically accurate), and fantasy. I actually start to get bored if I read too much of one genre, so prefer to buy books from a variety of genres. I do the same with music, get bored of too much of the same genre, so mix it up...rock, country, blues, jazz, classical, etc.
