'The Key to Peace' is a collection of letters discussing moral values through the lens of the Bible. The letters featured in the book are exchanges between a grandmother and her grandson. One day, in a very brief conversation, this author's grandson asked her a question. She did not get to talk with him much, so later she felt really inspired to write some things which were upon her heart, that his question had prompted. Of course, she has gone into more detail than she would have had to know, but felt it was good to stir up thoughts of what she did know. After she gave it to him to read, the author remarked that she might print it someday and hoped that it would be a help to someone else. He returned it to the author and she is sending it forth now with a prayer that these Bible truths will be a help to some soul.
