I’ve noticed a trend over the past few years. When I see an author’s name used in a book description, it’s surrounded by commas. Grammar be damned, that author’s gonna use a comma.

Don’t damn your grammar. Write it properly.

Which means… Instead of…
When sexy artist, Kerri Broadhead, meets ShapeShifter guitarist, Mitchell Voss, in a grocery store…

the only comma should be after the word store.

Or I’ve seen this lately, too:
Kerri Broadhurst, meets ShapeShifter guitarist, Mitchell Voss…

Still wrong! You’re not going to write
Dog, meets banana…,
Right?

Right?

So… don’t put a comma around character names.

NOW. There’s an exception to this rule, and that’s when you are singling out one person among a group of people. As in:
One of the guitarists, Mitchell Voss, stood out from the others.

Or
His sister, Sally, was the only one of the three who said the right thing.

This time, you’re telling us who the only sister was. You’re naming the person in question. Or… singling one out of a group.

Otherwise, lose the commas.
