Just No
In the first book of the set, Unapologetic the situation Cara puts herself into with River is not sexy, it is appalling. I could not read past chapter 2 for the pure reason that the relationship between Cara and River reminds me of a relationship of my own that more or less mirrors theirs. Although, unlike her, I was never foolish enough to allow such a manipulative and self-centered guy back into my life. I cannot truly express how many things I immediately find wrong with Cara just in the first few chapters, including the fact that she makes an incredibly huge mistake at the very beginning of the book.
Will definitely not read the other books.
