Well Below Heaven, Eliot Idyllwild

When seventeen-year-old Kelly gets herself sent to a boarding school in Idaho, she leaves behind her twitchy, thirteen-year-old brother Sammy and a secret, sordid mess. Sammy desperately wants to play football, but his mother forbids it. So, instead, he steps right into his sisters dangerous wake, falls in love with one of her old colleages, and provokes the sadistic ringleader--Kellys ex. He attempts an ill-conceived rescue mission, all while fiercely protecting his sisters secret. Its a recipe for mortal danger. Kelly has to fess up, sacrifice her future, and bring in the authorities. But will she do it in time to save Sammy from his own heroism?
