I've read the Priestley and Santoro biographies of Charles Mingus and loved them both for their detail. I had tried in vain to find an equivalent biography of Thelonious Monk, then this book appeared.
No need to say much: this book tells the story of Thelonious's life beginning with his immediate ancestors. Everything's here and, if you want to know who he gigged with and when, or who he recorded with and when, this is the book for you. You'll also find a good account of his family life and enough anecdotes to give a rounded picture of Thelonious Monk as a person.
I would say this book is an unqualified success. If you love Thelonious Monk like I do, I don't think you'll be able to fault this book.
