As the title states, the book is amazing for an introduction to analysis. The exposition is clear and motivated, full of examples, and the exercises range from trivial to challenging. Overall a very easy book to read, especially for self-study. However it is only an introduction, and it is somewhat incomplete for a full semester course. For example, the author omits mention of metric spaces, instead dealing completely on the real line, and for a typical first year analysis course, it is only really a supplement to a more challenging text such Rudin's "Principles of Mathematical Analysis." I would recommend this book to a high school or college student looking to get a taste of analysis before beginning a formal course in the subject.
