Driven by a fierce need to prove her worth, quick-thinking Emma Leigh talks her way into a dangerous assignment with the Pinkertons. Her mission: to go undercover and assist in capturing notorious gang leaders Frank and Jesse James.

Finn Christenson, a jeweler bent on recovering a stolen family heirloom and avenging his father's death, wants nothing to do with Emma. But Emma's and Finn's paths cross when the gang robs their train, and a split-second decision forces them to come together to accomplish their missions and survive among the West's most dangerous outlaws.

While Jesse James proves as charismatic as he is cruel, Emma and Finn realize danger closes in on all of them. With moral lines blurred, Emma and Finn must decide what justice truly looks like and whether the greatest treasure is something neither of them expected to find.

Adventure, action, and witty banter abound in the first book in award-winning author Tara Johnson's new historical Western romance series.
