Hey I've got a list so I'll get to it as soon as possible. But the book series is called the Dark Series by Christine Feehan. I also really like her Ghostwalker series. The first books are called Dark Prince and Shadow Game respectively. But yeah, they are phenomenal. She's amazing. I was introduced to te series 10 years ago and I've been reading them ever since. She's got like four series and she releases a book for each one each year. I don't know how she does it. But the Dark Series and the Ghostwalker series are the only ones I read. But I've heard the others are great too. But yeah.. each book has its own plot but she's masterful at weaving in a giant overarching plot that goes through all the books. It's a series so it helps to read them in order but you can read them individually just fine as well. But yeah.. I absolutely love the relationship dynamics in her books. You should definitely check it out! I could talk about that series forever!! I've never introduced it to someone who didn't end up loving it. And they are addicting. So I definitely recommend!!! And then we can fangirl over the books together.
