Real Truth. Real Quick. Live: What are the best christian books to read?

How do I distinguish a good christian book from a bad one? If God in Genesis 2:16-17 describes the conferences about the Tree of Life only to Adam-since Eve wasn't created until four verses later. Then are we just to infer that Adam told Eve about the Tree's consequences prior to her being convinced and eating of the fruit first? How do I distinguish God's voice and my thought? Can we hear the audible voice of God? How can I grow in my understanding of the Bible?
