I find that there are all different kinds of book descriptions available, and it depends on the author (or person marketing the book). In my opinion, I feel like there are pros and cons to a lot of these styles.
Some are a basic description of the book, and don't give much information about what it's like. Which can be good and bad, because it means you don't need to spend too much time reading it to find the plot, I guess. And the opposite is that sometimes they give too many details; such as times when the description can give spoilers to things that ought to be a surprise in the book.
Another instance is that sometimes it's a sample of text from the book, but doesn't really explain much about what the plot is. Which is another good and bad thing. Because, while it does give you a little bit of insight into how the author writes, you might be confused as to what the overall plot is about.
One of my primary dislikes is when the description will name drop other authors (, franchises, brands, etc). Such as saying that "this book is like Artemis Fowl meets Star Trek" (just as examples), or inserting the names really popular franchises, in the hopes that it will interest you in this product. In some ways, I feel like it's not helpful for me, because the author's work doesn't always live up to those expectations, even though they want us to think it's like those projects. Though, I can see why some might find them to be helpful. Because I know some of you just want to read books similar to ones you've enjoyed in the past.
So what are your preferences?
What are some things you like or dislike about them?
Are there any particular things descriptions say that you automatically buy a book (or put it on your wishlist)?
How about when the description lies to you, or misleads you in some way?
