Big time disappointment and update.
The publisher had great communication with me up until I finally sent them the PDF they requested to publish my book on Sept 28th, 2026, but haven't heard back from them since. Update- Since my review, a publisher rep reached out to say the large PDF file I sent via email was sent to spam and they were therefore not aware I had emailed them until the review. They have been in constant communication since that time and I'm satisfied so far. Will provide a final review once the book is completed.
