This omnibus edition begins with The Hitchhiker´s Guide to the Galaxy, in which Arthur Dent is introduced to the galaxy at large when he is rescued by an alien friend seconds before Earth´s destruction. Then in The Restaurant at the End of the Universe, Arthur and his new friends travel to the end of time and discover the true reason for Earth´s existence. In Life, the Universe, and Everything, the gang goes on a mission to save the entire universe. So Long, and Thanks for All the Fish recounts how Arthur finds true love and "God´s Final Message to His Creation." Finally, Mostly Harmless is the story of Arthur´s continuing search for home, in which he instead encounters his estranged daughter, who is on her own quest. There´s also a bonus short story, "Young Zaphod Plays It Safe," more of a vignette than a full story, which wraps up this completist´s package of the Don´t Panic chronicles. As the series progresses, its wackier elements diminish, but the satire of human life and foibles is ever present.
