Query: This book breaks slow and never recovers

Inaccuracies aside and there are a lot of them (Northern Dancer being referred to as Native Dancer, etc.) This book is poorly written, nonlinear storytelling being a major fault. The author jumps back in forth in time when discussing horses and races. There also is nothing really new revealed in this book as it's mostly a rehash of already well published facts. Finally it doesn't help that Wayne comes off as humorless and unsympathetic here as he does in real life.
