One definition of eschatology in Christianity is the study of religious beliefs concerning future and final events as described in the Bible. This has been a popular topic of late. If you don't want to get into the nuts and bolts of a Bible study, I'd recommend that you pursue the various LaHaye and Jenkins books about these times such as the Left Behind series. While fictional, I think they do a very good job of describing Biblical prophecy. On the other hand, if you want a more detailed study than what I will present here, I suggest you consider reading Dake's God's Plan for Man, or purchase a copy of Dake's Annotated Reference Bible. Both of these last two works cover the entire Bible in addition to his study of the end times.
There are a couple of sequences here. The primary one here studies Revelation and Daniel. You really can't cover Revelation without at least studying Daniel along with it. There are many other passages in the Old Testament that cover the millennium, but Daniel is critical for the time after the rapture through the anti-Christ's reign.
