Wyatt Hunt is temporarily bedridden and completely miserable. Somehow Molly Garner's limited skills have made her the most qualified in their circle to care for Wyatt. But by the time he's healed, she's fed up with him and the whole ungrateful family. For even worse than his grumpiness were the few unguarded moments when he pulled at her heartstrings, and she has long determined to never marry.

Molly gets a job as the housekeeper at Oliver Hawkins's ranch. But really she's with the Pinkertons, spying to find out if Hawkins has abused women and if he's guilty of murder.

Wyatt refuses to let her risk it alone, convincing Hawkins that he's abandoning his own ranch, angered by his two brothers' coming to claim a big chunk of it.

But when another Pinkerton agent gets shot, they realize Hawkins isn't the only danger. The Hunt brothers will have to band together to face all the troubles of life and love that suddenly surround them.
