Five friends head on a weekend mountain getaway. Only four will return.

A group of writers from Nashville piles into a car and heads to the mountains of north Georgia for a work retreat?and a bit of drinking and gossip. They've booked a cabin in the woods with no internet and no cell service, and hopefully, no interruptions.

Near the cabin the friends discover the beautiful but decrepit Catwood manor, abandoned decades earlier. Detritus from its final lavish dinner party remains on the tables. Writer brains spin with a thousand questions, but two stand out: Why did the Catwood family abandon their mansion during a posh affair? And why did they never return?

A dark cave near the house may hold the answer. But learning the secret to the family's disappearance will be deadly.
