Retire Rich From Real Estate

What is a good book on Real Estate?
I need to read a good book on Real Estate, I am a beginner. I want to learn from A-Z.
I have read ‘Rich dad, Poor dad’
‘Cashflow Quadrant’
& ‘Retire Rich, Retire young’
None of them are specifaclly on Real Estate, don’t know much about Real Estate. especially the Literacy.
I want to know should I read “ABC’s of Real Estate” by the Rich Dad company???
There are also 3 “Real Estate For Dummies” books available online for free:
