I must confess, that while I've read Kavalier and Clay 3 times and claim it as my favorite novel, I could not get into Summerland or The Yiddish Policeman's Union. Still, today I picked up and purchased Maps and Legends, which is Chabon's first non-fiction book, as well as a book that sports a triple layer wrap-around Jordan Crane cover.
I have to say that my somewhat unrelated motivation for buying the book aside from its packaging was Chuck Palahniuk's essay collection Stranger than Fiction, which I enjoyed immensely and often flip through at random. Like Chuck's book, I have almost no idea as to the stories I'm in for, which sort of makes it exciting in this age of blurbing and over-review.
I'll let you know how things shape out.
