The Menace from Earth

This is a strong collection of stories that I find more enjoyable than most of Heinlein's full-length novels. “The Year of the Jackpot” is probably my favorite Heinlein story, and “By His Bootstraps” is a classic, and very satisfying, time travel story. The eponymous story is memorable for its smart, tomboy main character and scenes of low-gravity flying as a sport on the moon. “Project Nightmare” and “Water Is for Washing” are also quite good.
