About a year and a half ago, my then 10 year old son, bought these books with his own money because they sounded like something he would like. (Knights and castles) He was raving about how wondererful they were and read the whole series in less than a week. My husband, wondering what all the "fuss" was about decided to read "The Sword, the Ring and the Parchment" too. He was so impressed and too, went on to read all 7 books, and recommended that I do too. I don't have tons of time to read, being a homeschool mom of 6 children, but I read every one of the books in the Terrestria Chronicles and was so blown away at not only how wonderfully written they were, but how incredibly they were able to explain our spiritual walk with God and encourage me in my own personal relationship with Him. Another great plus, or maybe THE best part, is that, having read them, we are able to use the books to refer to when explaining spiritual truths to our children. That has been so neat. I can say, "Remember Prince Josiah when he did......" and they can immediately relate and understand what I'm trying to show them. These books are worth their weight in gold. You will never regret this purchase!!! If your children love knights and castles, they will love these books. They are not just for boys though, either. My 7yo "girly" daughter begs me to read another chapter. It even keeps my 5yo's attention. Thank you Mr Dunlop for allowing God to work through you. These books, in my opinion, are much better than even Pilgrim's Progress! This book should be read by EVERY child and adult. It shows how subtle the love of money and materialism is and how it can take over your heart, lives and affections without you even realizing it.
