Monks and Mystics: Chronicles of the Medieval Church (History Lives series)
"Protestants tend to think of the Middle Ages as the dark and oppressed period between Augustine and Luther.  But God did not abandon his people for 1000 years!  Missionaries carried the gospel to foreign lands, the Bible was translated into various languages, and Christians held each other accountable before God.  Picking up where volume 1 leaves off at the close of the sixth century, these stories bring to life both the believers and the unbelievers God used to grow his church in the medieval era.  We hope you'll find the History Lives series an engaging, accurate introduction to the true story of Christianity." ~ Mindy Withrow
