We purchased this book and the study guide for our boys, ages 13 and 10, with hopes they would relate to it. The discussions that we had were amazing. The boys caught on to metaphors and were able to make a connection to keeping their hearts pure and how keeping scripture hidden in their hearts will might help them later in life. My husband and I are purchsing this book for every family with boys we have on our Christmas list as a family gift. I think it is great for boys of all ages, engaging, life affirming, fun and the illistrations are amazing. Each time you open this book you will find something new to talk about and another way to affirm your faith with your boys.
