Trollope the Oil Tanker?

I'm terribly confused. I just got one of those Amazon.com alerts where they try to sell you something that their software thinks you'll like, based on what else you've bought from them in the past. Except this one ...

Well, judge for yourself:

As someone who has purchased or rated books by Anthony Trollope, you might like to know that "Container Ships and Oil Tankers (Amazing Ships)" is now available. You can order yours for just $23.93 by following the link below.

(And no - the author's name is John Sutherland.)
