Query: Great storyline, but lacking execution

I thought this was a great book overall; the plot-line was sound and kept me interested. The only problems were in the author's writing style. I remember being frustrated by the random history throw-ins, and I also remember some awkward phrasing that made me shake my head sometimes. It is definitely worth reading through for the story, though.
