Part of my brain hunts down errors with a big stick and a shovel, it comes from writing, but I don't let them ruin my reading enjoyment unless they completely derail my experience-train. Let me give you an example. I won't expose the author since the work wasn't submitted for review, I'll just use a little bit under fair use.
"She had never before looked at herself in this manner and suddenly realized she would now be considered a young women back home and ready to be sutured by a young prince from a neighboring kingdom."
There. It doesn't really trip me that this girl has become plural (women), it's right after that. (BAM!) Sutured? Really? This character is uninjured at this point in the story and I can't seem to conjure any mental image for this that isn't, well, eeeewww. It took me a few moments to figure it out. Prince, aka, suitor. Oh, I get it, you meant Courted. Or possibly Wooed. Somebody let spell check fix a non-word into the closest thing it could find. The end result is that I'm reverse-engineering the author's intent and I'm not reading anymore. Not to mention that this is now the most memorable thing I took away from that particular story.
