Query: WHAT A DISAPPOINTMENT ! ! !

I picked up this book because of the author's previous work and ended up greatly disappointed. From the first chapter I could tell the story was underdeveloped, the characters were unrealistic and the dialogue didn't make any sense. I kept reading hopping that it would pick-up but no such luck. At the end I felt . . . . . . . cheated.
