Aroostine Higgins returns in a page-turning thriller from USA Today bestselling author Melissa F. Miller.

When a tourist reports an abandoned car at a remote trailhead at the Grand Canyon's North Rim, Aroostine Higgins is the logical choice to investigate the high-profile case. After all, it's her job. She's a consultant to the National Park Service Investigative Services Branch, and she specializes in tracking people.

But when a search of the car turns up a blood-soaked hat that's a match for a missing woman and a scrap of paper bearing the name "Rue Jackman," the case becomes personal. Under the alias of Rue Jackman, Aroostine helps find missing Native American women who've been forgotten by the system.

The only problem is the missing woman isn't Native, and Aroostine has no idea why her alias is on that piece of paper.
