"Timely, thrilling, and gripping from start to finish. An absolute page-turner." --Karen M. McManus, #1 New York Times bestselling author of One of Us Is Lying

Jay is living his best life at Karloff Country, one of the world's most famous resorts. He's got his family, his crew, and an incredible after-school job at the property's main theme park. Life isn't so great for the rest of the world, but when people come here to vacation, it's to get away from all that.

As things outside get worse, trouble starts seeping into Karloff. First, Jay's friend Connie and her family disappear in the middle of the night and no one will talk about it. Then the richest and most powerful families start arriving, only... they aren't leaving. Unknown to the employees, the resort has been selling shares in an end-of-the-world oasis. The best of the best at the end of days. And in order to deliver the top-notch customer service the wealthy clientele paid for, the employees will be at their total beck and call.

Whether they like it or not.

Yet Karloff Country didn't count on Jay and his crew--and just how far they'll go to find out the truth and save themselves. But what's more dangerous: the monster you know in your home or the unknown nightmare outside the walls?
