I have a special request from a young lady in my small faith group (an offshoot of our Catholic evangelism retreat). She's in her early 20s and has some difficulty reading. She's a convert to the faith, and she often struggles with some of the concepts we discuss. She asked if I could recommend some books for her so she can better understand her faith. Can any of you recommend texts that are simple enough in language that aren't necessarily directed at children? I'm hoping to find something on Church doctrine and something else on saints, devotions, or Catholic history.
