Gawd, here's a toughy! I'll have a crack, though if you ask me again next month perhaps some of the answers will be different!
The Master and Margarita - Mikhail Bulgakov
His Dark Materials - Philip Pullman
Watership Down - Richard Adams
Those three would always be named, they're all very special to me.
Midnight's Children - Salman Rushdie
Lord of the Rings - JRR Tolkien
The Blind Assassin - Margaret Atwood
The Blind Watchmaker - Richard Dawkins
Wise Children - Angela Carter
Independent People - Halldór Laxness
The True Deceiver - Tove Jansson
The only reason George RR Martin's Song of Ice and Fire isn't in there is because it's not finished yet, but unless the ending's absolute toss, it will be in whenever it's finally done.
