The New York Trilogy by Paul Auster
Summary from Goodreads : Paul Auster's signature work, The New York Trilogy, consists of three interlocking novels: City of Glass, Ghosts, and The Locked Room haunting and mysterious tales that move at the breathless pace of a thriller. I had a hard time composing my thoughts regarding this book. I don't think I can even tell you what the book is about because I am not entirely sure myself. Coming into this, I can't say I wasn't forewarned. I knew this would not be your straight forward detective story. And strange as this book was, I latched onto to in a way that I never thought I would. The three stories are separate from each other, but are connected in the sense that they all share the same tone and mood and theme. This trilogy still very much reads like a mystery novel. There are detectives and stake outs and disguises and shady people and supposed crimes and conspiracies. But what makes it different is that it deals with a case that seems unsolvable.
