Hitchhiker's Guide to the Galaxy Books in Order

Written by Eoin Colfer from Douglas Adams's notes, this sixth Hitchhiker novel picks up after Mostly Harmless as Arthur, Ford, Trillian and Random face yet another threat of annihilation, runaway bureaucracy, bored gods and the eternally insult hurling Wowbagger.

Arthur Dent washes up on a backwater planet and tries to build a quiet life, just as his old friends, his reporter ex Tricia and their unpredictable daughter Random are drawn into a last, bleaker twist in the Guide's story.

Arthur Dent returns to a mysteriously restored Earth, falls in love with the elusive Fenchurch and tries to make sense of vanished dolphins, strange memories and God's final message, in a more romantic, earthbound but still very odd Hitchhiker adventure.

Summoned from a sleepy exile, Arthur and Ford join Slartibartfast, Trillian and Zaphod to stop the fanatical robots of Krikkit from wiping out the rest of the galaxy, in a chaos filled mix of cricket jokes, time travel and cosmic sabotage.

After barely escaping a Vogon attack, Arthur, Ford, Zaphod and Trillian ride the Heart of Gold to Milliways, a restaurant built inside a time bubble at the universe's end, where interstellar politics, impossible coincidences and very bad decisions collide.

Seconds before Earth is demolished to make way for a hyperspace bypass, bewildered everyman Arthur Dent is whisked into deep space by his friend Ford Prefect and the starship Heart of Gold, stumbling into a funny tour of an indifferent universe.
