FBI special agent Eleanor Peters eagerly gave up her hollow life to go deep undercover in a crime syndicate family. Work was the only thing Eleanor had until the operation blew up in her face. Then, she had nothing.

Eight years later and hiding behind a new name, Kate Hall lives on the other side of the country from her past. Nicknamed Angel Kate, she provides a haven for weary Pacific Crest Trail hikers at Hostel Hall. The constant flow of strangers gives her all the company she needs.

But when her bloodhound, Jenny, finds a backpack with designer drugs inside and Reese Carson, special agent with the National Park's Investigative Security Branch, shows up to investigate, Kate's solitary life is turned upside down and inside out.

Convinced her deadly past has found her, Kate must decide if she should disappear again and protect the woman she loves or confide in Reese and fight a killer together.
