Are Marie Kondo's books good?

Marie Kondos books are very good. "Spark Joy" is perhaps the best of the bunch although other ones are good as well. She has quite a few out so her readers are enjoying quite a good selection. They are quite informatiove and will help the reader learn to organize in new and interesting ways using Chinese based techniques.

"Life Changing Magic" is another great book by Marie Kondo. It focuses on organization as well. She is a very good writer and a very good organizer so the two become one for the reader. Kondo has sold over a million books in many different countries. Her works can be found in English and in Chinese and yes, they are all quite good.
