A very disappointing read. Although this book will explain the power of real options I feel it does a very poor job of explaining how to evaluate them. Additionally the book has errors in some of its examples and in more than one place is incorrect. (ie spread option analysis) In several places it gives some theoretical values with no explanation as to how they were reached. I would only recommend you read the 1st Chapter in each section, as subsequent chapters just repeat the material but with a different concept. Definitely not for the person looking for a book with some meat on it. (Incidently several of the 'real options' they identify in the book or completely outdated. ie The afore mentioned spread option. People haven't used the method they suggest for many years as its mathematically incorrect.)
