Why are there no good books on embedded project management on the market?

I spent an afternoon in the bookstore yesterday and found some books on software engineering project management. It was found that some school professors had written books on paper and could not find practical books. These are all illusory theories that may not be used in actual projects. Maybe they don't even bother reading these books.

However, the only achievement in the afternoon was Lin Rui's book titled it enterprise project management: Problems, methods, and tools. It is indeed a good book that implements Lin Rui's language style, in addition, it is very practical to start from reality. It is indeed a street lamp for me to move towards project management. So I spent an afternoon reading it. I don't feel like a book ....

However, the disadvantage of such a book is that you can read it once. Reading again is the same .... If the content is more detailed and richer, I believe it can become a must-have book for everyone ......

I have been searching for a long time and have not found any books on embedded project management. Maybe those planning and editing books have to be moved to the market.
