Probably the best example I can think of is Diane Duane reworking her Wizards series to make it modern-day, but there are others, including owners of a literary estate altering books left to them to make them compatible with current standards.
What do you think? Does it matter if it’s the original author or an inheritor?
That’s the first thing I thought of too! The random modernizations are so jarring because everyone’s manner of speaking and all of the situations are just so retro.
