The Amazing Adventures of Kavalier and Clay
by Michael Chabon
This book covers the life and achievements of Sam Clayman and Josef Kavalier, from their childhoods (Sam in New York and Josef in Prague) through their primes as inventors of a cavalcade of comic characters, which not only made their fortunes, but created their lives. Covers the period from the late 1930s through to the mid 1950s. This book is superbly written. Merely engaging in the first 100 or so pages, its not till page 200 and onwards that it moves from being very good to being "unputdownable". The main messages are that being honest to yourself is more important than any outward projection, that sometimes friendship is the most important thing in the world, and that trust is about as valuable an attribute of friendship as you could want.
Can't imagine this book not being in my top ten books of all time.
