This hefty hardcover omnibus edition of Adams' work includes the first four novels and a short story:

Hitchhiker's Guide to the Galaxy
Restaurant at the End of the Universe
Life, the Universe, and Everything
So Long, and Thanks for All the Fish
"Young Zaphod Plays it Safe"

I bought it ages ago as a keeper copy, but while I loved the first two books and kinda-sorta enjoyed the rest, I think it's time the book went traveling.

I first encountered Adams' work via the delightful 1981 TV mini-series, and while I didn't care for the more recent film version, the story's still fun - and a foundation work in the humorous-fantasy-SF genre.

[The TV Tropes page about the series - including books, radio, and film - may be of interest as well.]

As part of the Towel Day Release Challenge in honor of Towel Day, I'm releasing this book at the gas station; I plan to leave it on top of one of the pumps at about 6:30 or so. Hope the finder enjoys it - and knows where their towel is!
