This was so good! I loved the found footage aspect of it. The different types of media (recordings, letters, etc.) really kept this story feeling fresh and exciting throughout the entire 400+ pages. 

I also loved that we didn't get a definitive answer about whether "the dead things" were real or not. The author sort of let the evidence speak for itself, and to me, it felt like it was up to the reader to decide if we believed it or not.

The only thing that took away from this being 5 stars was that the ending felt a tiny bit anticlimactic in comparison to the amount of build-up there was. But overall, this was an excellent read!
