A huge store isn’t the worst place to be stranded. There’s food and water, bedding and books. But what if it’s not safe to leave? Emmy Laybourne had us from the get-go with her utterly fresh and fast-paced debut. Six high school kids (some popular, some not), two eighth graders (one a tech genius), and six little kids are trapped together in a chain superstore. Together they build a refuge for themselves inside, while outside, a series of escalating disasters, beginning with a monster hailstorm and ending with a chemical weapon spill, seems to be tearing the world—as they know it—apart.
