Maybe this will wake her up:
2 Thess 2:11-12 “For this reason God will send upon them a deluding influence so that they will believe what is false, in order that they all may be judged who did not believe the truth, but took pleasure in wickedness”.

I wish it were that easy. She is not a Christian. More into Harry Potter and Steven King than any thing of God. :~(
