I would love an audiobook version (time/ability permitting)!
Have you thought about making a youtube video about the book? I get the majority of my book recommendations from booktube so it may be a way to keep reaching out. You have been doing a lot already. I’ve found it super interesting/helpful to read!
How many hours a week do you think you’re spending on book promotion? Do you squeeze it in during your normal work week or mostly work on it on weekends?
