The Book of Illusions by Paul Auster
This novel plunges the reader into a universe in which the comic, the tragic, the real and the imagined dissolve into one another. One man's obsession with the mysterious life of a silent film star takes him on a journey into a shadow world of lies, illusions and unexpected love.
I've been listening to the audio version of this book on my daily commute. I just finished it and I have to say that I loved it. Auster is an amazing reader (you never know what you're going to get when you have an author reading his or her own book) and is very believable as narrator David Zimmer.
David's own storyline is interesting in and of itself, but Auster augments it, intertwining it to splendid effect with that of Hector Mann, a silent film star who mysteriously disappeared in 1929, and (to a lesser extent) with that of 19th Century French writer François-René de Chateaubriand.
There was a moment when I thought that the ending would ruin the book for me, but at the last minute Auster ties things up marvelously producing an ending that is both realistic and satisfying for the reader.
