From the international best-selling author of The Shadow of the Wind.

Barcelona, 1957. Daniel Sempere runs the Sempere & Sons bookshop, is happily married and has a son. No longer the child who discovered the Cemetery of Forgotten Books, he is still haunted by the mysterious death of his mother when he was six years old. Meanwhile his best friend and accomplice, Fermin, is about to marry the love of his life. But something appears to be bothering him. One morning, when Daniel is alone in the shop, a mysterious figure enters and buys a precious copy of The Count of Monte Cristo. Then, to Daniel's surprise, the man inscribes the book with the words 'To Fermin Romero de Torres, who came back from the dead and who holds the key to the future'.

That night Fermin confesses that he was once in prison and that he had to fake his own death to escape. Now his former cellmate has reappeared with a possible key to hidden treasure. But is it a trap? And why is Daniel's wife meeting someone in secret? And who was the sinister figure Daniel's mother went to meet on the night of her death?

The Labyrinth of the Spirits is a stunning Russian doll of a novel, an addictive story that will lure you into a world of plots within plots, where even the shadows have a story to tell....
