Reading Pet Peeves

So I’m reading away the other night, totally engrossed in a really good book, turning the pages as fast as I can. When suddenly everything comes to a screeching halt and I’m ripped out of the story.

Why?

Because the author didn’t know her stuff. Didn’t do her research. And I caught it. I had to put the book down. Oh, I’ll finish it because I love this author and I love this book. But for right now I need to take a break from it because the mistake was something that shouldn’t have happened if the author had done the research needed. And it’s a simple thing to do. A quick Google search would have netted the correct usage of a word.

Note to contemporary authors: There’s a HUGE difference between jail and prison. The character, who happens to be a cop, would definitely know that difference, yet he used the wrong term and it pulled me completely out of the story.

So what is your reading pet peeve? What will make you throw the book against the wall and walk away from it?
