This is a collection of all 5 books in the Hitchhiker's Guide to the Galaxy series. And, it is the most RANDOM series ever written. And, I like it.
It starts off with Arthur Dent, an ordinary man, watching as his home gets destroyed to build a new bypass. Just as the earth is about to be demolished to make a hyperspace bypass, he is saved by his friend, Ford Prefect, who is actually an alien. It continues from there.
Since this series is so random it is also quite funny. I would recommend the first book to anybody, but the first is the best, and the 2-5th books all get more and more confusing and boring, and involves things like time and alternate dimension travel, which is confusing. I would rate the series 7/10.
