It is the early 1980s and fifteen-year-old Libby is obsessed with The Field Guide to the Trees of North America, a gift her Irish immigrant father gave her before he died. She finds solace in “The Kingdom,” a stand of red oak and thick mountain laurel near her home in suburban Pennsylvania, where she can escape from her large and unruly family and share menthol cigarettes and lukewarm beers with her best friend. One night, while driving home, Libby's mother, exhausted and overwhelmed with the fighting in the backseat, pulls over and orders Libby's little sister Ellen to walk home. What none of this family knows as they drive off leaving a twelve-year-old girl on the side of the road five miles from home with darkness closing in, is what will happen next. A Crooked Tree is a surprising, indelible novel, both a poignant portrayal of an unmoored childhood giving way to adolescence, and a gripping tale about the unexpected reverberations of one rash act.
