Query: Disappointing, Eagerly awaited and let down badly

Dyson sphere promised so much in a title taken from one of the best star trek episodes in the season, However the book takes too much time to explore the relationships between the horta and Picard that it loses it's way, Research is one thing but we readers don't want chemical analyses and atomic structure explained like we dropped out of high school chemistry, we want action and suspense, I waited months to get hold of this copy and now it is filed in the "Read only when depressed" section of my library. Believe me read this and you can throw your idea of a good book down the drain along with what ever you spent to buy it. Avoid this and go straight to the Double Helix series, Its a good read.
