After an undercover FBI operation blew up in her face, Special Agent Eleanor Peters disappeared.

Eight years later and hiding behind a new name, Kate Hall runs a remote hostel for Pacific Crest Trail hikers, content with the anonymity her new life provides. The constant flow of travelers offers all the human connection she needs?and none of the attachments she fears.

When Kate's bloodhound Jenny discovers a backpack filled with designer drugs, National Park Investigative Security Branch Agent Reese Carter arrives to investigate. Soon Kate's carefully constructed sanctuary begins to crumble.

As the walls close in, Kate faces an impossible choice: vanish again to protect the woman she's unexpectedly fallen for, or trust Reese with her secrets and confront the killer who's finally found her.
