No.
I did say maybe. It will be years from now and maybe by then I will be so discouraged from writing after the dismal audience response.
But If I do, I will try to include Wallace but no promises. I hate empty promises and I hate not carrying out my word so let's be safe and not promise!
I still am deciding whether I should do the modern one with the secretive family or do an ancient supernatural one like Dark tales. Either way, nothing is concrete yet.
Let me finish "The Forbidden City" first and then we will see what happens later.
Why don't you go and bug SS?
Or even better, get Ken Cheng to cast Wallace in his fanfic!
