Ashlynn Amuso is a thirty-year-old woman having the time of her life. She works for a great company in New York with her brother, Glen, and her two amazing friends, Kaden and Roman. Every year they get a two-month vacation from work where they go wherever they want. One year they went to Mexico. Another year was Florida. Another was the Caribbean. And now, Ashlynn takes them to her family's cabin in Lake Minnetaha, Washington.

It is the perfect place. Peaceful and quiet. No one around to bother them, a large forest in the backyard to walk around, and a small town not too far away for shopping and drinking. They couldn't have asked for a better vacation spot.

But one day, Roman, Kaden, and Glen start leaving Ashlynn alone in the cabin with no word of where they're going or what they're doing. They continue to do so until they leave the cabin for good. Ashlynn is distraught. She doesn't understand why they left, but she wasn't about to leave them behind. She stays, searching for them, waiting for them to come back. Unfortunately, while waiting, something finds her.

With the help from her friend, Jack, she learns that she is not going insane. That whatever she saw was not a figment of her imagination. But what is it? Who is it?
