My copy of
Tide of Empires: Decisive Naval Campaigns in the Rise of the West - 1481-1654 came yesterday. It was apparently meant to be the first of four volumes, but only two were published before Padfield started on his later series. I'm not sure if the two tie together or not.
One interesting note is the paper I found in the front of the book. I'm not sure, but it seems to imply that this is a first U.S. printing of the book, intended for submission to a reviewer. If so, I got a pretty good bargain for $13.99.
