From the New York Times best-selling author of The Program comes a brand-new haunting, romantic, and suspenseful story about one girl's search for healing in a grand and mysterious hotel full of secrets.

Stay tonight. Stay forever.

When Audrey Casella arrives for an unplanned stay at the grand Hotel Ruby, she's grateful for the detour. Just months after their mother's death, Audrey and her brother, Daniel, are on their way to live with their grandmother, dumped on the doorstep of a DNA-matched stranger because their father is drowning in his grief.

Audrey and her family plan to stay only the night, but life in the Ruby can be intoxicating, and they extend their stay as it provides endless distractions - including handsome guest Elias Lange, who sends Audrey's pulse racing.

However, the hotel proves to be as strange as it is beautiful. Nightly fancy affairs in the ballroom are invitation only, and Audrey seems to be the one guest who doesn't have an invite. Instead, she joins the hotel staff on the rooftop, catching whispers about the hotel's dark past.

The more Audrey learns about the new people she's met, the more her curiosity grows. She's torn in different directions - the pull of her past with its overwhelming loss, the promise of a future that holds little joy, and an in-between in a place that is so much more than it seems....

Welcome to the Ruby.
