The West Moon Chronicle

The elusive creatures of mud and blood known as the dokkaebi live just off of Route 4 in east Texas, in the ancient pine forest known as the Tanglechase. Joon-Ho, a Korean immigrant with a shadowy past, and his estranged grandson Jae-Sun are the only people in the nearby town of Vane who know the true nature of the dokkaebi. Together, they must figure out what's causing the creatures to turn hostile. Perhaps it has something to do with the interdimensional portal at the heart of the Tanglechase, for it is from here that the past comes knocking, demanding a reckoning from both men.
