A meteorite is hurtling toward the Black Hills of South Dakota. . . .
Brady Steele's love for all things extreme is given a boost when a fireball crashes through the roof of his house. It turns out that Brady's space rock is one of the rarest meteorites ever found. In fact, a professor from a nearby museum wants to study it in search of extraterrestrial bacteria, hoping to discover the first proof of life beyond Earth.
During a wild week of extreme bicycling, fishing, and caving, Brady discovers he's able to do strange and wonderful feats that shouldn't be possible. At the same time, he's developing some frightening symptoms. Could he be infected with long-dormant microbes from space? Is his meteorite a prize . . . or a menace?
