If you're a fan of those golden days when music was playing on spinning vinyl, you'll understand the reference. It was devastating and annoying when your favorite often-played 45 got a scratch and the same word or note would repeat over and over and over again.
It was grating on the nerves then and I assure you, repetitive words in a review bring forth the same teeth grinding reaction.
No one realizes it while in the midst of writing a review. The focus is getting those thoughts down and making your point. Once you do that, however, it's time to take a second look.
I've been helping out with basic editing lately and I discovered how easy it is to repeat the same word in one paragraph, even to miss the doing of it altogether. I realize it probably made sense initially, and even authors have to be wary of that same pitfall. After being bombarded with one particular word, I simply could not ignore the fact that it needed to be addressed and fixed.
The word that whomped me on the head was STORY.
If it's a funny romance, the word 'yarn' might even be applied.
If it's a novel plus book, then the word 'epic' might be used.
