Sophie may be clumsy as a witch and a little bit too snarky, but she's so funny and charming that she didn't need anything more to wake my interest in what she had to tell. 
 It's not the best beginning of a series I have read in my life, it's kind-of weak in the development, but it's funny, is good written and has a great main character... I hope the other characters, especially Jenna and Archer, get further developed in Demonglass.
