You know the drill: civility, intellectual curiosity, a love of your fellow man and woman. Okay, that last bit isn’t necessary. Some questions you might want to consider:
Is the true nature of God revealed to us, ever, and if so, how?
What is at the heart of prophecy?
What does it mean to be haunted?
The novel is written with a very specific structure surrounding point-of-view: Claudia and Rebekah’s POV is always in the present, and Hazel’s is always in the past, but moving forward in time until it meets the present at the book’s climax. Why did I choose this structure?
That should get you going. Cheers!
