Jack Martin (aka Dennis Etchison) retired from the film novelization business with this book, the only one not based on a John Carpenter movie, and he went out with a winner. Cronenberg's mind bending thriller is explored in great depth, better explaining the characters and their motivations. Cronenberg's script went through numerous versions and the changes show here, but in this case it actually strengthens the ability to study the film in greater detail. Required reading for all Cronenberg fans.
