That chunk of pages at the end of a book, where there is a sample of a few chapters of the author's next book, which depending on when you are reading the book the previewed book may or may not be published.
Personally, I NEVER EVER read the preview, especially if it is the next book in the series and here's why:
1. I HATE spoilers and a sneak peak of a book just feels spoilery to me
2. I don't like to re-read things necessarily. So, if it's a series and I know I am going to read the next book in the series, I just skip the preview. Or, if it's some unrelated title that I'm not sure about, I'd rather read the synopsis than a chapter or two.
3. I am in impatient person. Waiting for the next book is hard enough as it is, I am convinced that reading a snippet of a book that I want will only make the waiting worse.
4. I am worried a preview would influence my review. I am the type of person who drafts my review immediately after reading a book, whether it's in a notebook, on my phone, or on blogger. I am always a little worried that if I start reading a preview, I might get confused.
What about those preview books?
The freebies that allow you to read the first few (or more) chapters of a book for free.
Yup, I NEVER download or read those either. One time I accidentally selected one of these samplers in the "Read Now" section of Netgalley, luckily I realized it was just a sample before I started reading it and I quickly removed it from my shelves. (I wonder if this hurts my percentage?)
Anyways, I'm curious - How do you feel about book previews? What are your philosophies when you spot them at the end of a book? Do you download the free samples?
