I think it's a stretch, maybe such a comparison can be made after a whole lot of sales and after the other volumes in this series do well ... but this guy reads a lot of books and I will gladly and graciously accept the compliment.
I know I never would have read Clancy if it had not been available in the stores, so I am hoping against hope that somehow the book can be made available in the stores around the country.
If that happens ... then we shall see for sure how it does.
Regards.
