Located just forty-five miles north of New York City and isolated in the hills of Putnam Valley, Lake Oscawana is the perfect summer getaway. At least, that was what April’s mother told her when she dropped April and her brother off to spend the season at their uncle’s lake house. It wasn’t bad at first. April thought she might’ve finally found someone that made her feel like family and a place she could actually call home. But April grew worried when she found something living in the water. Something strange. Something growing. She wanted to tell someone and sound the alarm, but April would have to learn the hard way that not all monsters lurk beneath the water.
