This book is a collaboration between the two authors that follows time from the very creation to the time that is supposed to be the end of the world.
Basically, you have a Demon and an angel that discovers that there is an antichrist. Both believe this is the child of an American diplomat and so they set about trying to influence the child. Unfortunately for them there was a mistake when the babies were due to be swapped and they gave the antichrist to a family from England.
They only realised their mistake when the child reaches the age of 11 and the hell hound due to be sent never arrives with the American diplomat. It then leaves them are then working together to find the right child.
There is also a witch involved who is closer to the truth than the pair, but the work together in the end (well, they are in the same place) as time is due to end on planet Earth.
This is a hilarious book, and I would rate it as high as possible at 5/5. This is something that everybody should read because it is just so cleverly woven together. There are a good few characters to watch out for that will make you smile and think of Terry Pratchett. I can’t really comment much about Neil Gaiman because I have read none of his things. (I probably should)
The only thing I would say is that it is very British in its humour! There is something for everybody in their two make you smile, but the British probably smile bigger!
As for the adaptation, they did a very good job in translating what is on page 2 what appears on screen. I follow a YouTube channel called Lost in adaptation who would do a better job than me explaining this. When he gets round to doing this I will link the video so watch out for that if you are interested. There are differences but I would say that the things they added do not detract from the story or the feelings intended by the authors. It leaves not too much out either which is a good thing.
So, what are you waiting for? Go read it, NOW!
