Lord I hope there is a sequel to this story. I really enjoyed the pacing and I even enjoyed the fact that I found Sarah Flores initially annoying. However, and I am sure this is by design, Ellery was the more interesting character.
My only complaint is the ending. Although, it was a logical point to conclude the story, I wanted to know more. What happens between Ellery and her Dad,Meg, her career, the aftermath. Hence the desire for a sequel.
