Advice from an ancient.
There are a gazillion books out there for you to read, you will never read them all even if you live to be 1000. If you read a few pages of a book and the author has not conveyed the subject to you, has not made the complicated easy to understand for anyone, you do not have a good author, discard him and move on. When you find a good author read his works (Saints, Doctors, Popes, clergy, Catholic writers).
To learn error, you learn the truth from Catholic authors, do not read the errors by the authors of errors (Eastern Orthodox, Protestants, Mohamedans, Bhuddists, Hindus,..... ). Learn truth to discern error.
re: made the complicated easy to understand for anyone
Read The Incredible Catholic Mass by Fr. Martin Von Cochem, and then all his books. You will see an excellent example of someone who writes five different ways about a subject in just like one page, for five different minds (covering from the peasant to the Phd.)
