Ten-year-old aspiring geologist Henry Bower investigates the meteorite that crash lands in the hayfield, discovering a rock that will change his family, his town, and even himself. Henry has always been fascinated by rocks. As a homeschooler, he pours through the R volume of the encyclopedia to help him identify the rocks he finds. So, when a meteorite falls in his family's field, who better to investigate than this rock enthusiast--with his best friend, James, and his little sister, Birdie, in tow, of course. But soon after the meteorite's arrival, the water in Henry's small Maine town starts drying up. It's not long before news spreads that the space rock and Henry's family might be to blame. Henry is determined to defend his newest discovery, but his knowledge of geology could not have prepared him for how much this stone from the sky would change his community, his family, and even himself.
