This was a rip-snorter of a book, but I can't help but feel it was too long. Actually most of O'Keefe's books make me feel like this. Approaching a good wrap up point for the story, except no, there's another quarter of the book to go. She's excellent at ramping up stories - tension, release - but she repeats it too many times, so that by the time you reach the end you're a bit fatigued from all of the new obstacles that keep getting placed in the protagonist's path.
