A case of egregious misprinting

As a book reviewer, I often receive an assortment of various ARCs (Advanced Reader Copies) to browse through and, well, review. I'm sure a lot of you have had run-ins with an ARC at least once in your life. There are ALWAYS disclaimers that the ARC is an uncorrected proof, which generally only means that there will be typos or formatting errors.

However, I have never quite seen a misprinting as serious as this: the entire book was incorrect.

Whoa.

This is what happened: I requested a copy of The Poison Diaries by Maryrose Wood, based on a concept by the Duchess of Northumberland from Amazon Vine. I received it a few days later. The cover led me to believe this was the right book. After all, I've never had something like this happen to me.

Then I opened the book. The first page gives praise for The Olive Farm. The second page talks about a woman named Carol Drinkwater. The title page shows that this book is indeed The Olive Farm: A Memoir of Life, Love and Olive Oil in the South of France by Carol Drinkwater.

Whoa. That's not The Poison Diaries.

Now, I'm definitely keeping this book because it's so unique. I've never seen something so interesting as this. However, what I want to know is how this even came about. Here are the facts:

• The titles are not the same (The Poison Diaries v. The Olive Farm)
• The authors are not the same (Maryrose Wood v. Carol Drinkwater)
• The publishers aren't even the same (Balzer + Bray v. Penguin Books)
• The publication dates aren't even close (July 20, 2010 v. June 25, 2002)

I'd say those are some pretty big differences. So how is it possible a mix-up like this could even occur? I figured the printer must've made some kind of mistake, but a mistake this big? That doesn't seem very likely. 

Any ideas, anyone?

EDIT: I received a second copy of The Poison Diaries and it was correct (as in, right book!). It seems my The Poison Diaries/The Olive Farm was the only anomaly in the batch.
