(view spoiler)[THEY FINALLY GOT OUT! Took 'em long enough. (hide spoiler)] 
 The last book ended on a dark note. This book continues on an even darker note. Except the middle of this book dragged and had less plot than the last two books. 
 HOWEVER, it was good. The ending made everything worthwhile. What an action packed final few pages. What brainpower used by the characters. What excitement! 
 Alex is the same as ever; clever and dark. Zee is also the same as ever. Awesome. And the only character in this book that I'd actually like to get to know as a person. 
 Basically, this book carries on the good of the other ones to a smaller degree. It had everything they had, diminished by a little bit. Will I read the next, and (hopefully) last on? Definitely.
