This book was written by a ghost writer for Pat Garrett and set the stage for future Billy the Kid authors. The book is fictionalized in many places in an attempt to make the book flow better and to make the book more interesting. But, since the book was co-authored by Garrett, succeeding authors used it as a reference thinking he knew the kid well. But, Garrett did not know Billy as well as he led people to believe. The really good things about the book are the areas talking about Garrett's own experiences. But, the reader needs to be careful and not believe everything they read in this book. It could hurt them when reading more factual accounts of Billy's life in the future.
