Slogum House, Paperback/Mari Sandoz

Slogum House "lay on the winter flat of Oxbow like the remains of some great, hulking animal that had foraged the region long ago, leaving its old gray carcass to dry and bleach at the foot of the hogback." Ruled by Gulla Slogum, the house was headquarters for a clan that terrorized what it couldn't seduce or steal. Using her daughter as poisoned bait and her sons as predators, Gulla plotted to put a whole county under her control. She had been insulted too often and worked too hard; now she sought power, land, and revenge.
