Josie Gardner enjoys her quiet life. Supported by a sizable trust fund, she spends her days fostering shelter pets and exploring the streets of New York. She doesn't worry too much about the occasional creepy text from an unknown number... until the stranger shows up at her apartment door.
Between raising his two younger brothers and keeping food on the table, Jack Rizzo is in way over his head. Then he gets an offer he can't refuse: he'll get paid to move into the penthouse across the hall from Josie. His only job? To keep her safe from whoever is following her.
Neither is happy with the arrangement at first; however, in their proximity, Jack and Josie come to understand each other. As they toe the line between friends and more, they grapple with the reality of their different worlds - and the danger that looms closer every day.
