It wasn't great. But it wasn't terrible. Very meh. 
 I liked the idea of the story. It should have been thrilling. But it wasn't. 
 There should have been more diversity in the personality of the sisters. But there wasn't. 
 The ending though, was pretty fantastic. Just because of the last 20 or so pages, I want to read the sequel. I'm just hoping the characters will grow into more.
