When Marley Dearcorn finds the Houston brothers settling an argument over irrigation water by swinging fists and pointing guns, she isn't worried. The brothers have always solved disputes by punching first and talking later, so she leaves them to it. Then word reaches her someone on their ranch was killed after she left, and she wishes she'd intervened. Marley starts digging into the past strife in the Houston family, and she gets a lot more than she bargained for. A decades-old dark secret hangs over the Lazy Ox Yoke Ranch and the closer she gets to it, the more she begins to realize that years ago someone in the family tried to take the secret to their grave. Knowing the truth might reveal the reason behind the murder, but Marley is about to discover that if a secret is worth dying for, it's also worth killing for.
