One of the best ways to really wrap your mind around several topics in real analysis is to consider counterintuitive examples. The best way to understand why all the hypothesis in some of the most important theorems of real analysis are really necessary, is consider what happens when they are violated. This is precisely what this book is about. Exploring the most common counterexamples disproving all of the psudo-theorems students like to invent through blind, incorrect intuition. The selection of examples is exelent and the presentation is clear and precice. This is a great book.
