Are There Any Recommended Resources for Millennialism?

There's so many books out there and it's sometimes nice to have some clear direction as to where to go. Do you have any recommended resources for us? Yeah. Maybe one would be Augustine's City of God, the last several chapters in which he deals with things that we tend to associate with eschatology. Andres or Kim Riddlebarger has his book on all millennialism, understanding the end times.
