I purchased this first set of books to donate to our church library for the 8-12-yr-old age group. But before I purchased any additional sets, I wanted to read them myself to see what they were like. They were well-written, being easy to follow & read. I especially liked the books about Amy Carmichael and Gladys Alyward. These books show that if you let God lead you, he will also protect and provide for you. I will definitely order each set, but will first read them myself.
