The Stormchasers (edit title/settings)

Twins Karena and Charles share an unbreakable bond—and a devastating secret. Twenty years ago, 18-year-old Charles, who suffers from bipolar disorder, and his sister were out storm chasing when they collided with a motorcyclist. The two swore to each other they wouldn’t report the deadly incident to authorities; after all, they were legal adults and could do serious prison time. In the years that followed, the siblings disappeared from each other’s lives. Karena pursued a career as a newspaper reporter. Charles endured stints at various mental-health facilities and fed his true passion: chasing storms. (He always said that his mental state was akin to a tornado: terrifying and unpredictable as it spun out of control.) When Karena receives a distressing phone message about Charles, she ventures into the eye of the storm—literally—to find him. Blum (Those Who Save Us, 2005) intertwines two narratives: Karena’s search for Charles (and induction into the wild world of weather) and her recollections of their rocky childhood. The tales work together nicely in this moving, if occasionally overwrought, novel.
