My rating: 3.5 stars, rounded up to 4 stars.
This book, and the others in the Cynsters Next Generation series, is well-written -- but it is not as good as the earlier Cynster books. All of the books seem unnecessarily wordy, and this one is just far too long. Much of the detail of the plot could have been left out, and the story would not have suffered.
My main issue with this book is the mystery aspect. There was so much emphasis on it and the details of how they worked to stop it, that it almost overrode the romance. The earlier Cynster books usually had a mystery to solve, but the main story was always the romance -- in this series, in every book I've read so far, it seemed that the romances were very secondary to the mystery.
I also didn't like that the books, especially this one, were so long. A great deal of that length was due to unnecessary details of the mystery. That could have been covered sufficiently with much less detail.
Stephanie Laurens is an excellent writer, but this series so far has had too much emphasis on the mysteries -- and not enough on the romances. Since I read Laurens' books for the romances, I don't really enjoy so much emphasis on the mysteries.
My rating system is below.
1 star -- Hated it, or did not finish. I usually only give this rating if some of the content is truly objectionable to me, like if one of the main characters does something really awful, and gets away with it.
2 stars -- Didn't like it. This rating usually means that I thought the writing wasn't very good, the editing was terrible, I didn't like the characters, or it had other major flaws.
3 stars -- I liked it, but had some minor issues with it. This rating means that there were minor editing issues, the story needed more character development, it was just too unrealistic, or had some other fairly minor issue. The majority of books I read get this rating – I do not consider it a bad rating.
4 stars -- I liked it a lot. This is a high rating for me, and I rarely give a higher one.
5 stars -- I loved it, and will probably read it again. Very few books are good enough to get this rating from me. The ones that do are usually classics.
