So, it's been a couple days since I finished this book. I think I needed the time to digest. The night I finished it, I couldn't get it out of my head. It haunted me, in both a good way and scary way. I couldn't stop thinking about the characters and what they had gone through at The Peak and their encounters with black magic. At the same time, I was marveling at the intricately woven story that Pessl told.
