Trash Fire by Richard Bates Jr.

5.73

Owen and Isabel's love story simmers with spiteful rage and unfortunately for everyone, Isabel is pregnant with Owen's child. To prove to her that he can become a stable father, Owen agrees to reconnect with his only living relatives at Isabel's request. The couple take a trip to visit his perversely devoted grandmother and his sister Pearl, who was severely burned in a fire, to finally bury the hatchet. But sometimes the ties that bind can cut off all circulation.
