Nope. I'm of the market for boxing books at the moment. Got Bare Fists, James J Corbett and Chaos, Corruption, Courage and Glory "cluttering up" (not my words) the to do pile. I would be interested to hear about it though, a proper treatment of Billy Conn would be most welcome.
I've read it and its a very good, if slight, read, I'd recommend it although you may want to wait for the one later in the year, that may be a more detailed bio
There's a movie by the same name. It stunk. Henry Armstrong was in it for marquee value but to no avail.
Update. I've gotten both Conn books and IMO the SI article the Boxer and the Blond about Conn is better than both books as far as bio info. If your looking for fight breakdowns then get a book.
