Adams Douglas. So Long, and Thanks For All the Fish

Against all odds, at the eleventh hour, and in the unlikeliest place of all, the intrepid Arthur Dent finds the girl of his dreams. After eight years and about 100,000 lightyears of intergalactic travel, he is looking a little down-at-the-heels himself, and she is heavily sedated because she thinks she is a hedgehog. Fourth novel in the inexplicably inaccurately named "Hitchhiker's Trilogy" is the easiest to read so far, the funniest, and the most down to earth.
