Product Description Jim Marlowe's Martian pet, Willis, seems like nothing more than an adorable ball of fur. But Jim's devotion to the little creature will soon lead him and his pal Frank into a death-defying trek across Mars. 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." --KirkusReview of book: "Readers young and old will enjoy this fastpmoving adventure novel." --Chicago Tribune From the Inside Flap 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 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 Excerpt. © Reprinted by permission. All rights reserved. Willis The thin air of Mars was chill but not really cold. It was not yet winter in southern latitudes and the daytime temperature was usually above freezing. The queer creature standing outside the door of a dome-shaped building was generally manlike in appearance, but no human being ever had a head like that. A thing like a coxcomb jutted out above the skull, the eye lenses were wide and staring, and the front of the face stuck out in a snout. The unearthly appearance was increased by a pattern of black and yellow tiger stripes covering the entire head. The creature was armed with a pistol-type hand weapon slung at its belt and was carrying, crooked in its right arm, a ball, larger than a basketball, smaller than a medicine ball. It moved the ball to its left arm, opened the outer door of the building and stepped inside. Inside was a very small anteroom and an inner door. As soon as the outer door was closed the air pressure in the anteroom began to rise, accompanied by a soft sighing sound. A loudspeaker over the inner door shouted in a booming bass, “Well? Who is it? Speak up! Speak up!” The visitor placed the ball carefully on the floor, then with both hands grasped its ugly face and pushed and lifted it to the top of its head. Underneath was disclosed the face of an Earth-human boy. “It’s Jim Marlowe, Doc,” he answered. “Well, come in. Come in! Don’t stand out there chewing your nails.” “Coming.” When the air pressure in the anteroom had equalized with the pressure in the rest of the house the inner door opened automatically. Jim said, “Come along, Willis,” and went on in. The ball developed three spaced bumps on its lower side and followed after him, in a gait which combined spinning, walking, and rolling. More correctly, it careened, like a barrel being manhandled along a dock. They went down a passage and entered a large room that occupied half the floorspace of the circular house plan. Doctor MacRae looked up but did not get up. “Howdy, Jim. Skin yourself. Coffee on the bench. Howdy, Willis,” he added and turned back to his work. He was dressing the hand of a boy about Jim’s age. “Thanks, Doc. Oh—hello, Francis. What are you doing here?” “Hi, Jim. I killed a water-seeker, then I cut my thumb on one of its spines.” “Quit squirming!” commanded the doctor. “That stuff stings,” protested Francis. “I meant it to. Shut up.” “How in the world did you do that?” persisted Jim. “You ought to know better than to touch one of those things. Just burn ’em do
