Top 10 Best Selling Books 2019 Report | Shocking First Place

The NPD Group released a top 10 best selling books 2019 report covering the past decade of book sales in the U.S. Though they aren't yet classified the best selling books of all time, you can certainly see they're fast headed in that direction. And, it's an even better sample of what's to come in the book publishing industry.

Oddly enough, the #1 best selling book of the decade was originally self published. Can you guess what it was?
