Sharpshooter Preston Baker has spent a lifetime confronting danger head-on. So when a heartfelt letter arrives from his big sister asking for help, he doesn't hesitate to put his traveling show career on hold and journey to her remote desert ranch, determined to make amends for past failures. What he doesn't expect is to discover his long-lost little sister and her best friend, Lucy, are both hard at work on the ranch.

Unbeknownst to anyone, Lucy Arlidge's decision to travel to a remote desert ranch was born as much from desperation as friendship.

To thwart the evil plans of those who pursue her and her family, Lucy must keep her new gem-mining operation concealed and her secrets safe.

Preston is drawn to the mysterious woman, despite her plans to marry the neighboring rancher. Lucy's quiet strength and undeniable beauty beckon him like a campfire in the wilderness, offering light amidst the dark memories and deepest fears resurrected by the presence of his sisters. But as danger closes in, Preston and Lucy must confront their pasts to save not only their own futures, but the lives of everyone they love.
