Catholic apologetics, contrary to what it sounds like, is the defense of the Catholic Faith, not apologizing for it. If you've ever found yourself tongue-tied by a confident Bible quoting protestant or an antagonistic atheist, it's time for you to become a Catholic apologist.
Apart from explanations of what the rapture is really about, you can read inspiring conversion stories from people like Scott Hahn who was positive that Catholics were wrong - until he discovered they were right.
These books will help you learn both the "what" and "why" of the Catholic Faith so that next time someone tells you that "Catholics believe the pope is perfect" you can defend the Faith with the confidence of Patrick Madrid and say that being impeccable and infallible are not the same.
