Our view
“Mostly Harmless” is the fifth Hitchhiker’s book and the last Adams wrote, and readers generally rank it below the earlier ones. Some find that the first half idles and that the story, once it gathers speed, stops abruptly, though the clever, funny passages still land when they come. It is one for those who have followed the series this far and want to see it through, not a place to begin.

About the book
Mostly Harmless is a 1992 novel by Douglas Adams and the fifth book in the Hitchhiker's Guide to the Galaxy series. It is described on the cover of the first edition as "The fifth book in the increasingly inaccurately named Hitch Hiker's Guide to the Galaxy trilogy". It was the last Hitchhiker's book written by Adams and his final book released in his lifetime.
