I really wish I could take you up on this. How are the stories like? I hear that the creator actually knows about Tarot, that makes me think it won't be bad at all.
She seems to actually know about it, either through personal interest or maybe she researched it on her own. The deck the two tarot reading characters, the main character Pamela, and Cora, use real tarot decks (the Aquarian and the Chinese, respectively). The images used in the books are those of the real decks, so she at least had to have some access to that.
Also, in the first few books, there were mini-readings performed for various characters and several pictures in the reading throughout the reading are made by taking a related deck and transposing the characters into that card. For example, there's a vampire named Calic, who is on love with a woman, so she drew the Lovers card from the Vampire Tarot (by Hertz) but with Calic and the woman in the place of the people actually in the card. So, she at least has access to different decks. Perhaps she's a collector?
When the cards come up in a reading in the book, there's usually a side note as to the traditional meaning of the card. From time to time, Pamela will interpret the cards slightly intuitively, which I found to be a good thing.
