Has Donald Trump actually read this book he's recommending?

Far be it from me to suggest that Donald Trump is saying that a book about him is "really good" without actually having read it, but boy does it look like Donald Trump is saying a book about him is "really good" without actually having read it.The president praised 'The Art of the Donald, Lessons from America's....' (sic) on Twitter today, only that isn't an actual book.The Art of the Donald: Lessons from America’s Philosopher-in-Chief is, so what happened here?
