What an amazing book!!! If you haven't heard of it, it is about a man whose young daughter is kidnapped and murdered while they are on a camping trip. Her bloody dress is found in an old abandoned shack. Several years after her murder, her father Mack returns to the shack after receiving a letter from "Papa" asking him to meet there. It turns out that Papa is God. The entire book is about their conversations.
I highly recommend reading this book!
