Really a cool idea for a book. Clark, the author, runs KnuckleballHQ.com, so you know right off the bat where his heart lies about the fluttering pitch. He breaks the topic out into a few areas. History of the pitch, how to throw it, how to coach it, and how to catch it. Along the way he dispells a few myths & will likely win over even the most ardent knuckleball hater. Certainly not a thick book by any means, but a quick read and something you'll find yourself referring back to that is worth a home on your baseball shelf. ( )
