This is not an easy book, but it's a great one, well worth the effort, especially for serious readers. The main character is you, the Reader, as you seek a missing chapter, "traveling the earth from book to book." If that sounds mind bending, it's because it is! Calvino is a literary giant, on par with the likes of Borges and Garcia Marquez. Readers who are interested in trying Calvino but would prefer a lighter read would do well to pick up The Baron in the Trees. If On a Winters Night a Traveler, though, is a real masterpiece.
