Matt Fradd and I just met a few weeks ago. He recently worked for Catholic Answers and is now striking out on his own. He is an excellent apologist and has a delightful Australian accent.
He has recently written a book on how men can free themselves from addiction to the scourge of pornography.
Matt has posted parts of his book on-line here:

Part 2: http://mattfradd.com/2013/11/13/breaking-free-from-porn-a-5-step-battle-plan-part-2/
You can visit his website and buy the book for $2 here.
