Query: Who wants to read a textbook?

I'm really sorry to pan a book in a series I have come to like, but, as a lawyer who has to read altogether too many dry, hypertechnical documents a day, this was a real failure. I feel that the genre is ACTION first and foremost, and the complexity of this series is just simply getting in the way of the action. I am quite capable of achieving suspension of disbelief, and I don't need a textbook on the pseudophysics of time/dimensional travel to do so. Probably 80 pages of this work could have been directed to actions and adventure rather than trying to achieve an unneeded "scientific" basis for the way the characters get where they are going. I know Einstein says no going beyond light speed - maybe he is right but I still want to see Star Wars and won't care a bit about Einstein. Axler - its OK, we got to the new dimension - lets DO something there!!!!!
