A secular book that I would recommend would be "Beyond Positive Thinking" by Dr. Robert Anthony. It is not about child rearing specifically but helps the reader to understand his or herself and how he or she thinks. It's a fantastic book! I wish I had read this before my kids were born. It could have helped a lot.
Yes, and Bible stories. Dorling Kindersley has a great Bible for 10-12 years +; there are wonderful picture Bible stories for earlier. We loved these, learned so much together.
