Blake Laser. Daughter. Sister. Genius. Blake and her family are headed for a vacation out in deep space for some rest, relaxation, and a whole lot of family bonding time. It's uncharted territory, and Blake is excited for the new adventure. But the trip is cut short when the Interplanetary Space Control Center flags them down to warn them of danger. Someone-or something-is draining heat from the sun, threatening to plummet Earth to unlivable temperatures in just under forty-eight hours. The McClain family are the only ones close enough to investigate. They must put their trip on hold to figure out what's going on and, more importantly, stop it. If they don't, the fate of the entire planet hangs in the balance!
