How is Althea's father, Garth, described in the novel, Althea & Oliver?

Garth is described as, "A Southern gentleman from Savannah, where all of his family still resides, Garth quietly nurses--despite his outward trappings of erudite bookishness: reading glasses, ever-present glass of good scotch, and insistence on proper grammar--a fervent love of the lowbrow, particularly mass market paperbacks and poker."
