4.5 stars here. I really liked this one. (I don't agree with the blurb on the front by the Divergent author: "Never read anything like this", because I've definitely read a lot "like" this recently: scrubby girl discovers she has cool, dangerous superpower that will save the world, and gets to have a makeover, etc. etc.) The world of the book sucked me in, as did the heroine, who I truly liked and rooted for from the very start. ( And I adore Mal, of course.) I definitely look forward to the next installment:)
