Someone sane, with a College Degree, and Catholic please answer about L Ron Hubbard...?

I am Catholic, done plenty of research on my own, and fell in and out of faith. My question is I got this booklet written by L Ron Hubbard on the Beach yesterday from a gentleman who seemed articulate and and kind. My question is before I open this book and open my mind to it, what should I know about this author. Is it worth it to read or should I just fold my laundry...
