Hi! We are starting Module 2 this year, but our co- op will be doing the Middle Ages. My boys, ages 5 & 7, will participate. I have looked at the Module 4 booklist, but I am kind of hoping to save those for later. What are some other great Middle Ages books we could read together? Or, since it will be two years until we get to Module 4, would it hurt to read some of those?
