Michael Prasad knows that he shouldn’t go out on the Mars surface. It’s dangerous. His parents have forbidden it. And the overwhelming anxiety he is sometimes struck with when he’s in his space suit makes it nearly impossible for him to leave the safety of the colony. But when his best friend, Lilith, suggests they sneak a rover out one night, Michael seizes the opportunity to prove that he’s more capable than everyone thinks. During their ride, though, disaster strikes as a massive solar flare hits the planet, knocking out all systems and disabling the shields that protect Mars from the sun’s deadly radiation. Stranded miles from home with no chance of being rescued, dwindling supplies, and no way to protect themselves from the sun, Michael and Lilith will have to risk everything if they’re going to have any hope of getting back home.
