Um, that’s a hard one, because, for me, it depends on quantity. In other words, how well was the book written? If there are a few grammar errors in the entire book, then no, that doesn’t bother me. However, if there are several on a page, then I’ll stop reading the book, the same with other errors. I recently read a romance by a famous author, no names mentioned, half way through a secondary character’s name changed. After I figured out who the character was and because the plot and characters hooked me, I finished the book.
I did not complete that book.
As authors and readers, we do not expect perfection. However, when there are many mistakes, it becomes obvious that the author did not have it proofread by a professional.
So, in a nutshell, besides head-hopping, my pet peeve—too many mistakes!
What about you? What is your pet peeve? After a week, I’ll tally all the comments. Then I’ll post the results. Come one, come all. Come vote!!
