Any suggestions for a Medicate primer book I can buy?

Hello:  

I'm interested in purchasing a book on Medicare (first time enrollee)

, preferably one that is updated annually, like a copyright 2024 copy?  Does anyone have any firsthand use suggestions?  I'd like to stay away from websites, they seem to authored by insurance brokers; I know of the "Medicare and You" info from the SSA. I attended a 1 hour webinar, I'd like to get more details on the specific Medicare "parts" (a,b,c,d, etc.)Thank You.
