My bookish peeves are: (in no particular order)
1) Blurbs that give away too much of the plot.
I find blurbs that describe the plot in so much detail that you know what happens up to halfway through the book just from reading it. I seriously don't need to know half of the plot line just to make me interested in the book-that's why I want to read it!
2) When the next book in the series lets you down
I hate when I love the first book in the series and really look forward to the next book for months and then I get disappointed because it doesn't live up to my expectations. It seems that sequels are either a let down or are better than the first in the series but they're never equal.
3) Shop assistants who seem to be clueless about the books they work with
Sometimes, when I'm browsing in a book store I overhear another customer asking for example where they can find a book in the store or a parent asking for recommendations for their children and the shop assistant seems to be pretty clueless. They're supposed to be the experts but often they seem to have no interest in the current book market or know what they're talking about. Of course, I know that there are bookshop assistants who are really dedicated to their work and passionate about books too!
4)Stickers on the covers of books or black marks on bargain books
It's very irritating to get a brand new shiny book from the bookstore or online and to find it has a sticker that leaves a horrible residue on the cover or a black mark on the pages to show it was selected as a bargain book. If there really is a need for this, it would be much better for it to be more subtle or for stickers to be easy peal.
5) When the models or illustrations on the front covers are completely different to the characters that are described.
It makes me wonder whether the cover artist read any of the descriptions of characters or conversed with the author at all when this happens. I find that it most often happens with girl's hair colour, for example a ginger haired girl is shown with blonde hair. I can't think of any specific examples at the moment but I know there are lots around.
6) When the cover design theme changes half way through a series.
