In the Wild West, gunslingers populate the legend of many a dime novel. And Renn knows her way around a gun—and a book—better than most of them, including her famous brother, who can credit his skills to Renn.

So, when the strange little men show up looking to hire her missing-in-action brother, Renn takes the job. And she soon realizes she'll need every bit of her gun skills and book learning to finish it.
