This is my all time favorite novel. It's hard to believe John Ross kept his day job and hasn't written another book.
It has been rumored that Henry's Bowman's escapades were to continue in a new novel, but alas I have heard that Mr. Ross has some medical issues... I would love to have Bowman become a character like Clancy's Jack Ryan but I don't think that's going to happen. UC was hampered by the physical size of the book, making it a very popular and beloved book, but not a cash cow for the publisher or author by information and belief.
However, if I may presume to make a suggestion, if the book is unprofitable to PRINT, perhaps an E-book priced around 10-17 dollars US would be..... Bears some thought, but it depends on the legal contract Mr. Ross made with the original publisher... It would definitely put a crimp in the pockets of the SCALPERS that are selling such a great book for such exorbitant prices without ANY BENEFIT to the man who labored to create it.....
Cheers,
Scott
