I figured that since it was a complete rewrite (and from another
author), I'd start a new series. But I also understand your point.

To not confuse others, I'll mark the next one as V2 instead (if that's

I'm really sorry! I actually completely missed your response there. 

Thank you again for reviewing! I know it's a lot of work sometimes...
