Keller Mitchum has already lived a lifetime in eighteen years. Fully responsible for her five-year-old sister Parker, Keller has seen and experienced things in life that should exist in the most intense fictional plot. Wise beyond her years, she will do absolutely anything to keep Parker safe.

Garrison Davies is a twenty-three-year-old pilot in Massachusetts, working with her father in a small, family-owned cargo business. Independent, feisty, and brilliant at what she does, she makes little time for anything outside of her beloved planes and dogs. Her simple and structured world is turned on its head when a difficult situation lands two unexpected guests into her life and her house.

Garrison tries to make a safe space for Keller and Parker, only partially aware of the horrors they come from. As time passes, it becomes clear that it's not only the past that keeps the two sisters at arm's length. Can Garrison break through Keller's defenses and help her regain control?
