Did you plan all along to make a sequel to This Is Not a Test? Or did something trigger that desire...?
I am so sorry for the delay in answering your question! I'm resolving to get better at my Goodreads Q&As. I didn't have a firm plan to write a sequel to TINAT, but I knew the open-ending would always make a sequel a tempting possibility. One day that possibility got the better of me. I love zombies, and I love exploring that world. :) Thanks for asking!
