The cover and page quality make this book a joy to read compared to other derivatives texts on the market.
Even more important, Dr. McDonald's writing is clear and logical. His theory is current and well laid-out. Compared to Hull it has more PDE's and sound theory. Compared to still other derivatives texts, Dr. McDonald gives more applications to supplement the theory.
If I could only recommend one derivatives texts to students and practitioners needing a thorough overview of the market, this would be the one.
