Christian Fiction? I think it borders on the occult?

Any book can be misused the fact is you have to be able to make up your own mind. If you would let a book persuade you how to think, then either you do agree with it or are looking for something and will latch onto anything that sounds rational. If you are not strong in faith then I would say you should read it, see the other opinions of this world, it will either strengthen your faith because you are so against the other opinions, or it will destroy it, which means you were never a true believer in the first place and was lying to yourself because you had no alternatives to turn to.
