Among the things I liked about this book were the return of some characters of previous installments, and the addition of some interesting ones. What I didn't like -and the reason I'm not giving it five stars- is that everything that happened was way too convenient to be believable. No political issues again, which is something I like but starts to be implausible when you see the big picture. Maybe that's what the next book will be about? Whatever the case, I have already pre-ordered it and can't wait to get my hands on it.
