I've been a fan of Paul Auster since his New York Trilogy, and oh my god he didn't disappoint with this one. Okay be aware, it's a 900 pages novel with small fonts. Whenever I bring the book people thought I was bringing a dictionary around LOL. However, the long narrative justifies the beauty of Auster's writing. He proved once again he can change from the detailed thought process of prose in New York Trilogy to a historical and storytelling style in this one. I loved the fact that he took that risk and produced a wonderful plot with a complex structure. 
 "The torment of being alive in a single body was that at any given moment you had to be on one road only, even though you could have been on another, travelling toward an altogether different place"- Paul Auster 
 This quote alone reflects what Auster wanted to do with this novel. 
 4321 is about not one main character but 4 different main characters with the same names until we discover the real meaning behind this book, and it was.. mindblowing! The stories are so good, reading so easily that I've been totally compelled, with a slice drug-effect addiction to it. You may be scared about the length and ask yourself what the fuck is going on? But if you can spot all the subtleties of where the author was going with it, it makes the reading experience absolutely addicting. 
 Thank you to Penguin Random House for giving me a copy of this book for review!
