This book is for fans hungry between two volumes of the comics. I read comics and watch TV series and I always appreciate the very particular world, and it is a little between the two stories (comics / TV series), which allows to work better secondary characters and parts of story not covered in the other media. We discover a piece of history from the perspective of "enemies" Rick and his band. This is a plus for those who want to know everything about this fabulous series. The book reads easily and style is very basic, the characters are more developed but the fun is not the same as with illustrations, suspense and psychological pressure felt much less strong. It therefore does not expect to discover the same with the comics.
