This was a weird book. Not that is wasn't enjoyable because it was. But what makes it weird is the reader is at a loss as to if the character of Amber was malevolent or benevolent. Were the characters that encountered Amber's unique form of "friendship" better off by knowing her? Who was Amber? Where did she come from, where did she go? Was her visit premeditated? All these questions are left ultimately to the imagination of the reader. And what about that ending? What was that all about?
