Blood & Hate is a very engaging story about Hagler's upbringing and rise through the boxing ranks. Wedge does a thorough job detailing the bleakness Hagler lived in and overcame through a combination of his tight knit family and unbelievable willpower. The bond with the Petronellis has been covered in other sources, but Wedge seems to flesh out the earlier years in further detail. While "hate" is in the book's title, Wedge documents the support system that clearly loved and respected Hagler.
I like to read detailed accounts of fights in boxing books. Wedge's blow-by-blow account of the Hagler-Minter fight is one of the best I've ever read. Unfortunately, the other fights Wedge covers are reduced to short summaries. These fights, especially the Philadelphia fights that served as Hagler's trial by fire, deserve more detail.
Be advised, this is not a book about the "Four Kings" rivalry. Hagler's fights with Duran, Hearns, and Leonard are dealt with in five sentences in the book's epilogue. Since these fights have been documented in-depth in numerous books, I can appreciate Wedge's focus here on the early part of Hagler's career.
Boxing fans definitely need to read this.
