Some thoughts as I read:

I've noticed people commenting on Delialah's back-sliding in growth. I too started to think that way, but then a thought occurred to me. She's always been the weaker one, the younger one emotionally, more naive. She HAS grown, by leaps and bounds. But if you truly follow the series, then the last book and what her oldest sister, the "rock" of the three went through, then you have to take that into account. Though it physically happened to Camille, emotionally I think Delilah lived it as well. And I think it's also important to note that Delilah isn't as sexually open as her sister. This too could impact Delilah in terms of the rape Camille suffered at the hands (talons/claws) of Hyto.

One other note-there are quite a few errors in spelling and grammar. I've also noticed a few transposing of letters, and at one point, when Delilah is speaking to Shade about the fun atmosphere of the night before being interrupted by a phone call, she states the call came from Chase, when it actually came from Yugi. Chase was in attendance at the festivities.
I'm thinking, that because there is such a high demand for her books now, her publishers are pushing Yasmine Galenorn a little to hard. And as a result, the editing process is suffering.

In the end, after finishing the book, I'm glad Delialah's whining stopped. There were fewer errors deeper into the book. I'm satisfied with the story. I'm glad they got back to the meat of the issue, something that was forgotten in the previous book. I will stick this series out to the end, because I'm committed. However, interest is waning a little bit.
