Hey-
This book's been out of print for years and JFK will not authorize re-printing. There are also, unsubstantiated, rumors of his campaign team buying up all copies which may explain why those that appear on ebay are fetching in excess of $500.
What the Kerry camp probably didn't figure on was the internet.
Now, for your personal reading pleasure,
