THE PRISONER OF HEAVEN returns to the world of the Cemetery of Forgotten Books and the Sempere & Sons bookshop. It begins just before Christmas in Barcelona in 1957, one year after Daniel and Bea from THE SHADOW OF THE WIND have married. They now have a son, Julian, and are living with Daniel's father at Sempere & Sons. Fermin still works with them and is busy preparing for his wedding to Bernarda in the New Year. However something appears to be bothering him. Daniel is alone in the shop one morning when a mysterious figure with a pronounced limp enters.
