An interesting, fairly recent one is: "I Heard You Paint Houses": Frank "The Irishman" Sheeran & Closing the Case on Jimmy Hoffa, by Charles Brandt. I think I reviewed this a while ago. While not a bio of Hoffa per se, the author recounts how he was brought into the Teamsters Union by mobsters, got very close to Hoffa, played a role (he says) in the JFK assassination, and participated in Hoffa's murder. I don't say I believe everything in it, but it holds your interest.
