The book is very close to be published. After a few rounds of proof checking, the book is in a great shape for publication. Personally, I expect two more rounds of proof checking, which will be quick in turn over time. So, the publication date of December 7, 2023 is a very realistic target date. The publication date had been delayed from February 1 to December 7, 2023 many times over the course of the year. This might have caused readers some anxiety. But, it seems that December 7 is a realistic target date for the publication of the book. In any respect, the book is very close to be published. So, the wait is almost over!
