Query: Certainly Not Christian

Sad, sad book. I feel like I wasted my time reading it, and certainly my money buying it. I am very interested in Bible prophecy and thought this is what I would be reading about with this book Lamb. But instead I was ripped off by heretical garbage. I wonder if I could get some of my money back by selling it used?
