I have to say I didn't think I was going to like this book that much but after the first few chapters I really got into it. I absolutely loved the characters. Sloane was smart, emotional, scared and rebelliousness enough to keep me liking her. I like that she didn't just fall right into the ways of the program willingly and she was determined to stay herself. She wanted to know her past and not lose her memories no matter what it took. James was not only a good counterpart but he had his own emotional issues to deal with and work through. There were times I even liked him better than Sloane. He was supportive and likable. He was not only a loyal friend to her brother Brady but he also was devoted to Sloane and truly loved her. 
 Even Realm whom I really wanted to hate by the end had a sort of likable quality to him. I suppose he was meant to or Sloane wouldn't have called him a friend before or after she forgot the things she knew about him. 
 No book is perfect but this one came pretty close. I was thoroughly satisfied when I got to the end and can't wait to read The Treatment though I'm skeptical it will be as good.
