Well actually,i read the first 3 books in the serias about 2 years ago and i really don't remember that much,but i remember the names and the events,and i must say i laughed alot from this one and the other two after him,the serias is a funny Sci-Fi,the people who will enjoy it very much is a people with alot of humor,and Sci-Fi fans that don't really like all the drama Sci-Fi with all the understandable science facts,that is what this book is all about.it has a funny plot,characters and events all over it. the reason i only gave it 4 stars is because it's too damn short! i'm used to read books with 300-600 pages! what i'm gonne do now is buy the whole serias (i already got the second one and the third),and read it in a raw like a one book,maybe u should try it!
