This seems like a good place to ask: Anyone know of any good books about the Church Fathers? Or early Church history in general?
I would start with the life of St. Anthony of the Desert, written by St. Athanasius (you get two Patristic Fathers for the price of one!) It is a nice little book put out by TAN books. Additionally, I think Mike Acquilina has a three-volume series on the Patristics, which if I am not mistaken he put out with OSV. I haven't read it, however, but Mike tends to be very good.
Now it's on to Faith of the Early Fathers by William A. Jurgens, which is supposed to be an excellent series.
Also Eusebius, the Church History by Paul L. Maier is supposed to be very good.
And of course, there's The Didache.
