How has no one mentioned Isabel Allende yet? She practically created the magical realism genre. Adriana, I would highly recommend reading any of Allende's books if you are interested in surrealism/magical realism. And, although her memoirs are obviously non fiction, they are incredible, moving masterpieces of the human spirit.

Fludd and by Hilary Mantell. She's now famous for Wolf Hall but this early book of hers is just wonderful. Also Into Black by the same author

The Minotaur Takes a Cigarette Break by Steven Sherill

Good Omens by Pratchett and Gaimon

Totally with you on Too Loud A Solitude - I spend a lot of my time in the Czech Republic and they love the surreal. Of course there is always Kafka

There are some really great anthologies, though not so “contemporary”: Black Water, ed. Alberto Manguel; The Literary Ghost, ed. Larry Dark; What Did Miss Darrington See?: An Anthology of Feminist Supernatural Fiction, ed. Jessica Amanda Salmonson.
