Wow! I started reading this earlier this afternoon and could not put it down. It's easily the best of the bunch...although I could have done without the 'to be continued' ending.
For some reason I was under the assumption that this was the final book in the series since the whole time we've been building up to the Everafter war. That'll teach me to make assumptions, right? ;)
Anyway, I loved the fact that the author chose not to go with the 'Sabrina and Daphne's parents are awake and everything is all sunshine and roses,' concerning the family's reunion. The fact that things were rocky to begin with went against the cliché and it worked really well in the story.
I'll admit that the identity of the Master took me totally by surprise as did the other revelation made at the end of the book.
And once again, Puck is hands down the my favorite character.
So...bring on book 8!
