Last book I read was technically 4:
Ursula K. Le Guin - Earthsea: The First Four Books
I really enjoyed them! I don't read as much as I want these days but I enjoy it when I can. Next I should get on and read Philip Pullman's The Book of Dust (Part One: La Belle Sauvage), I bought it ages ago but never got round to reading more than the first chunk of it...
