Something amiss with Amazon recommendations

From today's Amazon email:

As someone who has purchased books by Theodore Sturgeon, you might like to know that British Foreign Policy under New Labour will be released soon. You can pre-order your copy by following the link below.

Theodore Sturgeon? Science Fiction author. All I can figure is that one of the books I bought was edited by Paul Williams which is the same name, if not person, as the author of British Foreign Policy under New Labour. Maybe I should buy it? I don't think so.
