Hideaway - BY Penelope Douglas

Buried in the shadows of the city, there’s an abandoned hotel called The Pope, surrounded by a mystery about the hidden twelfth floor and the guest who never checked out. Banks knows the local legend, but Kai Mori believes the myth around the hotel. He and his friends think they know her, think they can scare her, but Banks knows something they don’t. Even though she struggles to hide everything she feels when Kai looks at her, the person he seeks is much closer than he’ll ever realize.
She’ll never reveal her secret. This Devil’s Night, Kai will be the hunted one.  
But Banks doesn’t know what Kai had to turn into to survive three years in prison. He wants the hotel, its guest, and his life back. But the more he’s around Banks, the more Kai realizes this new version of himself is exactly who he was meant to be.
Kai’s seen her hideaway. It’s time for Banks to see his.
