Hello!
Yes, you can still work through your courses and modules without your book. Be sure to check your spam folder for updates on the UPS Tracking number so they sometimes end up there. I would definitely recommend reaching out to our Customer Support team to let them know that you are still missing your book, and they may be able to give you updates or expedite a new one for you.
All the best and don't hesitate to reach out if you have more questions!
