From Holden Caulfield to Moses Herzog, our best literature has been narrated by malcontents. To this lineage add Peter Jernigan, who views the world with ferocious intelligence, grim rapture, and a chainsaw wit that he turns, with disastrous consequences, on his wife, his teenaged son, his dangerously vulnerable mistress—and, not least of all, on himself. This novel is a bravura performance: a funny, scary, mesmerizing study of a man walking off the edge with his eyes wide open—wisecracking all the way.
