Overall I really enjoyed this story even though at some parts I was like 'You gotta be kidding me...' My main problems were the love triangle (was that really necessary?) and some of Marguerite's decisions. Sometimes it seemed like she didn't think at all and sometimes she was thinking too much. Fortunately I didn't hate her and I liked the other characters more. 
 The concept was really interesting and I enjoyed reading about the other dimensions. One thing that I would really like to know is what happens to the other Marguerites when she has left them. How do they feel? Did that "visit" change them? Basically I found the other Marguerites more interesting than our main character Marguerite. 
 I really want to continue on with this trilogy? and know how everything is going to be solved.
