I absolutely loved the anime of Cowboy Bebop. This book is set in the same universe with the same characters. Their stories, however, have changed. The way we meet Ed, Faye, Ein, and the history of Spike and Jet are different based on the author's take on the characters. Some might not like this, but I like the new twist on their relationships. Plus the author has added a whole new badguy! Since the TV series is over, it is also like getting all new Bebop stories. I haven't read the rest in this manga series so I don't know how they continue, but if you are dying for more Spike and don't mind the alternate reality, I highly recommend the book!
If you don't want the stories to change, consider picking up the Cowboy Bebop series by Hajime Yadate and Yutaka Nanten, ISBN#1931514917, simply called Cowboy Bebop Book 1 etc. These are more like continuing adventures that take place in between what would have been a TV episode.
