In Oak Knoll, a verdant, tight-knit North Carolina neighborhood, professor of forestry and ecology Valerie Alston-Holt is raising her bright and talented biracial son, Xavier, who’s headed to college in the fall. All is well until the Whitmans --- a family with new money and a secretly troubled teenage daughter --- raze the house and trees next door to build themselves a showplace. With little in common except a property line, these two families quickly find themselves at odds: first, over an historic oak tree in Valerie's yard, and soon after, the blossoming romance between their two teenagers.
