Query: Best Seller????

I've just finished "Zero Coupon" and I'm glad I can now move on to something more imaginative. I found myself reading this book so that I can finish it and pick up my next novel, not because it was interesting (I hate to leave anything unfinished). This could have been a much better book if the author had taken the time to give depth to his characters. It seems that he was more interested in establishing the scams and explain high-finance, which was interesting; however, the writing that put the story together left much to be desired. This very well may be the worst book I've ever read!
