I read all the books in the series. They are chick books. I have to say that I really liked these books. The author did an extremely thorough job of researching the material. It was evident that a lot of effort and time had been put into gathering the information and presenting it in an engaging way. However, there was one aspect that I could have done without, and that was the romance-novel sex scenes. They seemed a bit out of place and didn't really add anything to the overall story for me. I understand that they might be a part of the genre, but for my personal taste, I would have preferred if they were toned down or even omitted altogether. Despite this one drawback, I still enjoyed the books and would recommend them to others who are interested in the subject matter.
