This book I found in a second-hand store (cost: 50 eurocents)End of Days was not one of the best Arnold Schwarzenegger films. However it was still enjoyable Arnie action film and also starred great Gabriel Byrne as the Devil.The novelization gives a bit more back story for Jericho Cane, he was previously a SEAL-soldier working on black operations. Some of the characters are a bit different looking (for example Christine is blond in the novel and brunette in the film, and detective Marge is redhead in the book but black woman in the film). Also the end of the book is slightly different than in the movie.The book was a quick read (it lasted about as long as the movie). As a movie tie-in it was quite average.
