I have to say, I normally wouldn't consider writing a review for a text book. But this one is good.
In most of the financial classes I've attended, I am usually left scratching my head when introduced to new concepts because the text is so dense and the examples provided very rarely explain it enough. This textbook is so well-written that, although much of the material builds upon concepts introduced in earlier chapters, reading the earlier chapters isn't entirely required to understand the subject matter: each chapter stands on its own.
Also, Higgins's style is reminiscent of those fine classic textbooks from the mid-20th century, such as Elements of Style by Strunk & White and The Intelligent Investor by Benjamin Graham, interjecting dry, and at times belly-laughingly funny, humor into the text.
This book deserves to be a classic.
