It is the summer of 1968, but for Marion Goodman, a 62-year-old widow from Wisconsin, life on her Summit Road farm is miles away from the strife of the nation, until one evening when she aims her rifle at what she thinks is a coyote and instead discovers a runaway teenage girl foraging in her garden. Despite an inner voice warning her not to, Marion acts on her impulse to be generous to those in need. In doing so, she unwittingly solders the link of a chain that will bring others to her door-a girl fleeing abusive foster parents, a draft dodger with a growing list of crimes, and a young man truly without a home. When the three converge at summer's end, Marion's once-safe haven is threatened by a sociopath's violence and revenge.
