Set in the Niagara Falls of Craig Davidson's imagination-known as Cataract City-the superb stories of Cascade shine a shimmering light on this slightly seedy, slightly magical, slightly haunted place. The six gems in this collection each illuminate familial relationships in a singular way: A mother and her infant son fight to survive a car crash in a remote wintry landscape outside of town. Fraternal twins at a juvenile detention center reach a dangerous crisis point in their entwined lives. A pregnant social worker grapples with the prospect of parenthood as a custody case takes a dire turn. A hardboiled ex-firefighter goes after a serial arsonist with a flair for the theatrical even as his own troubled sister is drawn toward the flames. These are just some of the unforgettable characters animating this stellar collection that crackles with Davidson's superb craft and kinetic energy: in the steel-tipped prose, in the psychological perspicacity, and in the endearing humor.
