The Hollow Kind by Andy DavidsonRead about another entry on the list.
Old-growth forest in Georgia: Nellie Gardner and her eleven-year-old son, Max, leave everything behind when she learns that her estranged grandfather has left her his estate—the Redfern farmhouse, a mill, a thousand acres of forest. A sinister presence in the house and forest forces Nellie to unravel the Redfern’s violent legacy, and she finds she must do everything in her power to protect her son. The blood-soaked and eerie forest is home to much more than the family legacy, though—something ancient and waiting.
