I have to say I loved this book. I could not put it down. Chase was a wonderful character and Seven was quite possibly the most damaged and funny character I have ever read and loved. He had shut himself away to stay safe until Chase. The secondary characters were what made this book. It was a book of lost boys. Who had been locked away. The love between three and four. It was so gratifying that after everything they had gone through in the gray world they were locked in they could still feel. (view spoiler)[I had gave up on Thirteen's survival until I saw the title of the next book I also so want Nine to live. His body is out there (hide spoiler)] the ending was wonderful even though it ripped your heart out.
