My sister and I are staying at my uncle’s lake house. She found a treasure map that’s leading us to something sickening

This summer, I’ll be staying at my uncle’s lake house.

My parents decided it’d be good for my sister and I to ‘escape technology for a bit’ – experience the outdoors and whatnot. So, they’re sending us to my uncle’s. Despite not wanting to go, I’m actually fine with staying at the lake house; judging by the pictures it’s beautiful there, and I’ll get to explore the surrounding woods which really appeals to me. It’s just, my uncle – Uncle Curtis.
