In 2015, Booklist observed, "the arrival of Hauser's annual boxing review is akin to Christmas morning for fight fans. Nobody knows a sport any better than Hauser knows boxing."

Each year, readers, writers, and critics alike look forward to Thomas Hauser's annual collection of articles about the contemporary boxing scene. He's one of the last real champions of boxing and one of the very best who has ever written about the sport.

A Hard World continues this tradition of excellence with dressing-room reports from big fights like Canelo Alvarez vs. Miguel Cotto, a behind-the-scenes look at Floyd Mayweather vs. Manny Pacquiao, and a foray into the world of mixed martial arts for a compelling portrait of Ronda Rousey. Most importantly, this new collection contains Hauser's groundbreaking two-part investigative report on the relationship between the United States Anti-Doping Agency and boxing, a report that shook the industry and raised fundamental questions regarding the integrity of USADA's drug-testing procedures as applied to boxing.
