The first graders of Pod 1 are buzzing: It's Martian Health Week! They are learning about the 450 food groups. They are practicing for the space race. Only poor Nergal is so nervous he ties himself into knots (literally!). With help from his teacher, parents, and podmates he learns that nobo-one is good at everything, and what matters is that he try his martian best.Shana Corey and Mark Teague add another warmhearted, funny installment to their martian chronicles, with a reminder that being nervous is normal--even on Mars.
