After the explosive beginning of the first book in series, not much happens in this second entry. Even so, it's not a "filler" book. As the story plots on, you get the very real sense that pieces are being moved into place for a much bigger showdown in the future - which filled me with so much dread I could barely even enjoy the ride because I was so worried. My heart can't take this slow, suspenseful build-up. 
 My one criticism is this: I too am a huge fan of this thing that is slowly building up between Meg and Simon, but NOT at the expense of Simon becoming "more human." What is delightful about this world is precisely the fact the the Others are clearly not humans, and that humans are NOT the underdogs or the misunderstood species in this here series. We are here (well, I am) solely for the Others and their distinctly non-human understanding of the world as they navigate new relationships with humans. I'd be very sad to see Simon lose that just so he can be with Meg,as if being Other is not enough. 
 And the brilliance of this series is that Ms. Bishop has written it as a true urban fantasy, so that while the romance aspect is a nice, and enriching addition, it doesn't take too much away from the story if it's removed. Friendship works just as well. 
 Nevertheless, a solid, enjoyable, suspenseful offering.
