As mentioned earlier, I was surprised to find a Prologue. Maybe all Harper's books have them, but I don't remember and didn't go back and check. This Prologue, however, was particularly interesting. No names, no places are provided, and only the hint of "weak light" and "sea spray," but we have a definite conflict set in place immediately. Before I even started to read the novel I was on edge. What a clever and spell-binding beginning, and it's impossible to tell who is the most vulnerable character: him or her. And as readers move right on to Chapter One, they find the first word there is a name: Kieran. We have an immediate introduction to the novel's protagonist, and at the same time we have reason to believe he is in danger or may be the cause of it for someone else. This novel is IMPOSSIBLE to put down after an introduction like that!
