The Angel's Game by Carlos Ruiz Zafón

This book is set in the same world as The Shadow of the Wind--marked especially by the Cemetery of Forgotten Books--but it is set a generation earlier. David Martín is a successful author of lurid gothic tales; many of his friends feel he is wasting his talents, but he's locked into a long-term contract with a publisher who's especially interested in only the lucrative side of his talent. An interested (and apparently rich and influential) publisher, Andreas Corelli, offers to get him out of his contract in order to sign another deal. As Martín delves into the work though, he notices disturbing similarities to the life of his old house's previous owner (a lawyer-turned-writer). Many of the twists in the story were shocking, and I loved its thorough investigation of what we give up when we sell our talents. There were great layers of moral complexity in this story.
