The Battle siblings are used to disappointment. Seven years after starting her PhD program—one marriage, one divorce, three cats and a dog later—Theresa Battle still hasn't finished her dissertation. Instead of a degree, she's got a houseful of adoring pets and a dead-end copywriting job for a local candle company.

Jeff, her so-called genius older brother, doesn't have it together, either. Creative and loyal, he's also aimless, in both work and love. But his new girlfriend, Kim, a pretty waitress in her twenties, appears smitten. When Theresa agrees to dog-sit Kim's puggle for a weekend, she has no idea it will be the beginning of a terrifying nightmare that will shatter her quiet academic world.

Soon Kim's body is found in the woods, and Jeff becomes the prime suspect.

Though the evidence is overwhelming, Theresa knows that her brother is not a murderer. As she investigates Kim's past, she uncovers a treacherous secret involving politics, murder, and scandal—and becomes entangled in a potentially dangerous romance. But the deeper she falls into this troubling case, the more it becomes clear that, in trying to save her brother's life, she may be sacrificing her own.
