Has anyone ever had this happen to them?

Someone who's name I never heard of sent me a book as a gift. The book is about 200 pages, but the content could have easily fit in 100 pages or less. Also, page 3 says "printed in the USA", but the last page says "printed in Germany by Amazon distribution". The text is very generic self help stuff. My conclusion is this book was probably written by AI, and someone is sending out copies to get it to the best seller list. Holding the book doesn't justify the current price of € 46, and leafing through it doesn't give me the impression that it's dense in information, it looks to be just generic stuff.
