"We can't tell you how much we appreciate the Christian values and Godly principles you write about in your books. It means so much to us to know that other people are concerned about making the right choices and growing closer to Jesus. Your books have not only provided us with entertaining adventures. Most of all, they have encouraged and inspired us to stand up for God and the truth."
