Actually, her first couple of vampire books were pretty good, though not recommended for children. Then they started to go downhill, as she no longer seemed able to convey as an author that evil is, well, evil. Which I thought was the point of the earlier books.
Although I am a Catholic, I found no interest in her books about Jesus, written after conversion. I was pleased for her, but thought the books were feeble. They didn’t sell as well as the early vampire books, either.
Well, I’m sorry to hear that she has relapsed once more. Prayers for her.
Maybe it’s like professional wrestling, and she “became a Christian” to generate more publicity and book sales, and then “changed teams” again to appeal to her old fan base.
