    NASA, NATO, and the UN sent explorers to the asteroid's surface...and discovered marvels and mysteries to drive researchers mad.For the Stone was from space--but perhaps not our space; it came from the future-but perhaps not our future; and within the hollowed asteroid was Thistledown. The remains of a vanished civilization. A human--English, Russian, and Chinese-speaking--civilization. Seven vast chambers containing forests, lakes, rivers, hanging cities...And museums describing the Death; the catastrophic war that was about to occur; the horror and the long winter that would follow.

    and expert at seeing the cosmos on 30 Altairian dollars a day. Ford lives by the Guide's seminal bit of advice: Don't Panic. Which comes in handy when their first ride--on the very same vessel that demolished Earth to make way for a hyperspacial freeway--ends disastrously (they are booted out of an airlock). with 30 seconds of air in their lungs and the odd of being picked up by another ship 2^276,709 to 1 against, the pair are scooped up by the only ship in the universe powered by the Infinite Improbability Drive.But this (and the idea that Bogart movies and McDonald's hamburgers now exist only in his mind) is just the beginning of the weird things Arthur will have to get used to. For, on his travels, he'll encounter Zaphod Beeblebrox, the two-headed, three-armed ex-President of the Galaxy; Trillian, a sexy spacecadet he once tried to pick up at a cocktail party, now Zaphod's girlfriend; Marvin, a chronically depressed robot; and Slartibartfast, the award-winning engineer who built the Earth and travels in a spaceship disguised as a bistro.Arthur's crazed wanderings will take him from the restaurant at the end of the Universe (where the main dish of the day introduces itself and the floor show is doomsday), to the planet Krikkit (locked in Slo-Time to punish its inhabitants for trying to end the Universe), to Earth (huh? wait! wasn't it destroyed?!) to the very offices of The Hitchhiker's Guide itself as he and his friends quest for the answer to the Question of Life, the Universe and Everything ... and search for a really good cup of tea.Ready or not, Arthur Dent is in for one hell of a ride!

    Now, as faster-than-light drive opens the stars to exploration, humans are finding other relics of the race they call the Monument-Makers - each different, and each heartbreakingly beautiful.

Then a team of scientists working on a dead world discover an ominous new image of the Monument-Makers. Somehow it all fits with other lost civilizations, and possibly with Earth's own future. And distant past. But Earth itself is on the brink of ecological disaster - there is no time to search for answers. Even to a question that may hold the key to survival for the entire human race...
