Life, the Universe, and Everything is the third book in the Hitchhiker's Guide to the Galaxy series. In this sci-fi comedy cross, the maincharacter, Arthur Dent has almost gotten used to his life. True, the Earth was destroyed by aliens, and he was dragged around the galaxy by Ford Prefect his friend and Zaphod Beeblebrox, the three-armed, two-headed ex-president of the galaxy, but he hadn't seen them in months (or years) since he'd become lost on prehistoruc Earth in a very odd series of events. This time, however, he was sure that he was rid of them for good. He was wrong. Over the course of the book, Arhur Dent finds himself in a terrible predicament as he, Ford Prefect, and a mysterious man called Slartibartfast try to stop the destruction of the universe at the hands of an ancient xenophobic race of aliens that attempted to destroy the universe aeons ago. The three of them have to collect five items scattered through time and space to reassemble the 'Wikkit Gate', and ancient symbol with which they have no idea how to use. Along the way, Arthur meets up with a deranged character named Agrajag, who claims that Arthur has been killing him over and over again. Arthur is perplexed until he realizes that he had indeed been accidentally killing all of this poor man's reincarnated forms again and again. Full of excitement and wonder, and of course some good laughs, Life, the Universe, and Everything is my favorite book in the Hitchhiker's Guige to the Galaxy series. I would reccomend this book to all ages, whether you love sci-fi, or just want to laugh, this book is excellent.
