The first review of Mudville was posted over at kidliterate.com. It’s a nice one, too (why else would I link to it?)
The voice is great here – Scaletta’s really got the 12 year old thing down. The plot’s got a very nice flow to it – there are a lot of surprises in this book, and some of them could have been jarring. They weren’t. He weaves the sports and the family and the mystery together with the same careful stitches that close the leather on a baseball, with the same end result: a lot of game in one small package.
