A fan of my books, called Patricia, wrote to me recently to say:

"I have just finished reading and listening to the Zom-B series. I absolutely loved it! B quickly became one of my favorite YA characters, and I thoroughly enjoyed the way you approached her, the other characters, and the story as a whole. Even though I am nearly 40, I find that your creativity and way with storytelling continually draws me back to your writings.

"I feel a little bereft though, now that I have finished the Zom-B series, and I am absolutely dying to know more about xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx. Are you planning any sort of spin-off series? If so, do you have any idea when you might begin to publish it? (I sincerely hope you are.)"

I had to redact part of Patricia's email, so as not not spoil the big finale for those of you who have not read the books yet. Basically, without giving too much away, the way the series ended, there was room to tell another story -- but I don't ever intend to. I was very pleased with the conclusion, and the fact that it left readers wondering and asking questions about what might happen next. I felt I walked away from the story at exactly the right juncture, so I can't see myself ever returning to it. Why mess with perfection?!? :-)
