REDHANDED by Michael Cadnum
The Man Who Once Played Catch With Nellie Fox by John Manderino
Redhanded is about 2 brothers that get into boxing. Basically the whole book is them getting to the top of Boxing. Really good book.
The Man Who Once Played Catch With Nellie Fox is a bit of a twist. The cover leads you on as a childrens book but when you start reading it... Woha. Very good book though.
