This book started off strong--lots of mystery, interesting character problems, intriguing plot. Unfortunately, by the end of the book, it felt like the author had gotten tired of her own story and just started wrapping things up. For instance, the main character has a rather unique problem. It's introduced as this huge, important quality at the beginning, and later on it's treated as a very serious thing that maybe might not have any good resolution at all...and suddenly everything seems to be working out fine, let's focus on this other big problem that's the main plot of the story and forget that we made this other thing a big deal in the first place.
I also don't really appreciate books that are supposed to be part of a series and make it obvious with this "Oh crap! New problem introduced in the last two paragraphs! Let's go on our next adventure!" thing. No. You can set up a sequel and still have a satisfying resolution to your novel.
