Here at Halo-Works, we've been asked so many times what a good book is for thus-and-such a subject. We decided to include a page that shows what books we think are essential for a well-informed Catholic Christian's knowledge of religion, society, the seen and the unseen both in the physical and the spiritual world. 
Because the books presented are merely our own opinions, please do not take the following titles to be anything other than that--our own opinions. Also, we may or may not carry the books listed. Maureen gets her personal books that we don't carry used, and one of her favorite resources is Amazon.
