Why be Catholic. Ten Answers to a Very Important Question by Patrick Madrid
I still feel in-between Catholic and Anglican, so I found the Papal infallibility a bit difficult to deal with. However, I actually like the Catholic reverence for Mary - the usual problem for those who want to convert or convert. I enjoyed his chapter on this. I also especially liked his chapter on the saints and how many saints were great sinners. He mentioned some saints who I certainly want to research, for example, Pelagia, who was once a promiscuous actress!
This is recommended for Catholics and anyone interested in becoming Catholic.
