This is the third book of this series that I have read (besides "Magic in the wind" and "Safe Harbor"). The others sisters didn't seem interesting enough for me to buy their books. I loved the first, didn't much like the second and bought this one with doubts. I actually liked it a lot; it was interesting, the plot kept my attention and the characters were likeable. I think it managed to avoid the two worst mistakes that writers make when writing a series: a) it focused on the hero and heroine. The sister's bond is an integral part of the books, but each book is supposed to be a romance, about one couple's love story not about the sisters, and b) it was not used to set up the back story for the next one. Feehan had done both those mistakes with "Safe Harbor"; the sisters got so much "screen time" and the Joley/Ilya relationship was such an interesting subplot that I ended up finding Hannah's story a bit boring!
Two things I would have liked to see in this book: One is more details about Ilya's background; I couldn't understand where exactly he was raised and by whom. Apparently, these people were villains who abused him as a child in order to train a killer, but he somehow ended up a policeman. How did this happen? A scene where he shares his past with Joley would have filled this hole nicely. The other is that the whole thing with Joley's "dark needs" is not explained very well. The way I saw it was that she is an essentially good person, but feels less worthy, because she compares herself with her sisters, most of which are too good and nice and proper, and she eventually comes to realise that being different doesn't make her bad. That was very intriguing, but it was only implied, not shown.
