Three interplanetary explorers arrive at the yardangs of Mars, a series of spellbinding rocky ridges that have been shaped by centuries of wind erosion. But the team runs into trouble when their portable navigation device gets damaged! Surrounded by inhospitable landscape, the explorers must rely on their knowledge of the animal navigation or risk getting stranded. As the team brainstorms ideas, Malcolm sketches out and imagines the yardangs as a haven for Martian predators. This graphic novel includes Mars facts and survival tips as well as in-depth content on animal adaptation and behavior. Backmatter includes an activity page and character information.
