The Agony of Alice

Question:
 
I just started re-reading the entire Alice series in preparation of the final book. I just noticed that the first two books were written 4 years apart. Was “The Agony of Alice” meant to be a stand alone?

Phyllis replied:
 
Ah!  An observant reader!  Yes, I had no idea when I wrote the first one that there would be a series.  It was only after I heard from reviewers and fans that my editor and I decided to make it a series.
