Very unlikely! I have only read the first two, but I feel the first one stands on its own way better than as part of a series. Also any sequel to something as dreamy and weird as Wizard of Oz couldn’t help but over-specify and nail down all the charming stuff of the first book. So I am trying to present the one book as its own thing. Also it’s a huge amount of work and I got other stuff I want to do.
Glad you like the project thank you!
