Shadow of the Wind by Carlos Ruiz Zafon.
An engrossing read which relates the story of Daniel, son of a Barcelona book-seller who takes the boy to the Cemetery of Forgotten Books - an ancient Library. Daniel may choose one book, and takes 'The Shadow of the Wind' by Julian Carax. The boy becomes fascinated by the book, and, growing up, is consumed by the sinister secrets which surround the life and death of Caras. He sets out to discover the truth, and finds himself involved in a desperate race to save those whom Carax left behind. Beautifully written, atmospheric, and immensely readable.
