LOL...sorry, I have to laugh because the same thing happened to me. I don't even recall the book. I think it was a Nora Roberts book right when I got my Nook on Christmas Eve. I got about a page and a half to read. Some samples do their intended job and some don't!
I mainly have the problem with non-fiction and the B&N Classics. Even if they provide 20-30 pages in the sample, a lot of times that doesn't get you past the introduction. I won't buy a book based on the sample unless I actually am able to read part of the BOOK itself.
Reminds me of the "sample" I downloaded for Misery.
Page 1 - Cover
Page 2 - Table of Contents
Page 4 - Title
Page 5 - America Loves
Page 8 - More books by Stephen King
Page 11 - Inaccessible, [End of Sample]
... it's not exact, but pretty close. Terrible, terrible "sample".
If you're interesting in getting a look at the actual contents (not just - "does this ebook work for me?" as many people who buy technical ebooks are forced to ask before buying), I would suggest google books - a very broad page selection of content from the book. Same with Amazon.
