A Deadly Promise — Joan Lowery Nixon

As Sarah Lindley's father lay dying in her arms, he found the strength to whisper a cryptic message. Sarah vows to clear his name of the murder he is wrongly accused of committing, and now she cannot leave the lawless mining town of Leadville until she fulfills her promise. Unwilling to involve Clint and Jeremy, the two men vying for her affection, Sarah works against time to decipher her father's message and find the hidden evidence. With her younger sister, Susannah, more of an adversary than a help and the members of the conspiracy determined to find the evidence before she does, Sarah resorts to action that puts her life in jeopardy.

Will Sarah uncover the truth? And even if she does, will her enemies allow her to live to expose them?
