I was surprised at the amount of emotion I felt in this book. I didn't think I liked the characters but yet, I was very emotional when things happened to them. We never get to know Gabriel at all. Maybe that's my opinion but All we know about him is that he cleans vomit, delivers food trays and likes boats. The end. Linden is harder to explain but still the MC never seems to really know how she feels about him---so how am I supposed to feel? The writing is addictive in this series but despite my emotional turmoil in some parts of the book, I don't feel like I knew any of the characters at all. And, the craziness of the "evil" one (Housemaster Vaughn) was a little off to me. It's almost like I was reading book propaganda on the dangers of medical intervention in the world. 
 Rhine was WAY too passive for me. And what was up with Madame? Are we supposed to forgive her for what she did in Fever? What in the world? I feel like this series had me all over the place. I didn't know what to think about any of the characters. Maybe I am on angel's blood?
