Description:

Jim Marlow and his strange-looking Martian friend Willis were allowed to travel only so far. But one day Willis unwittingly tuned into a treacherous plot that threatened all the colonists on Mars, and it set Jim off on a terrfying adventure that could save--or destroy--them all! *From the Paperback edition.* ** ### Review Review of book: "A fascinating story of Earth-humans on Mars . . . the most thrilling and tingling kind of science fiction story by an experienced hand." --*Kirkus* Review of book: "Readers young and old will enjoy this fastpmoving adventure novel." --*Chicago Tribune* ### From the Publisher Like many people, I go way, way back with Heinlein. My very favorite book (and one that stands out in my mind--and with much affection--to this day) is Tunnel in the Sky. I really, really wanted to go off to explore new worlds with a covered wagon and horses, like the hero does at the very end of the book. But one of the nice things about Robert Heinlein is that he's got something for everyone. One of my best friends has a different favorite: Podkayne of Mars. Go figure.                         --Shelly Shapiro, Executive Editor
