We recently purchased a bulk quantity of Al Kresta's book Why are Catholics so Concerned About Sin? and WE'RE GIVING THEM AWAY! You don't need a coupon, you don't need a special code you just need to spend $10.

From the back of the book:

To those on the outside, Catholic teaching sometimes seems incomprehensible.
To those on the inside, it can be nearly as mysterious:

How many can answer the question, "Are Catholics saved?"
What is the Catholic position on "the rapture"?
Do Catholics take the Bible literally?
And what about confession? Does it really help a person change?
What about hell? Does the Church actually believe that it lasts forever?

In clear, straightforward language, the author answers these and many other questions that perplex Catholics and non-Catholics alike.  If you're wondering about the ins and outs of certain aspects of Catholic teaching, Why Are Catholics So Concerned About Sin? provides some answers.

Al Kresta is president and CEO of the Ave Maria Radio Network and the author of Why Do Catholics Genuflect? .  As a veteran broadcaster, he has fielded numerous questions about Catholicism from callers on his nationally syndicated radio talk show, Kresta in the Afternoon .  He and his wife, Sally, live in Ann Arbor, Michigan, with three of their five children.
