A better title for this book would be All About Duration. It is an elementary book about duration, convexity, extensions of these and various related topics. There are chapters on key rate durations, duration vector models and principal component durations. Other chapters cover topics in fixed income mathematics—term structure construction, interest rate futures, swaps, FRA's, etc.

While these are applied topics, the book's treatment of them is largely academic. The authors display little familiarity with or concern for how things are done on actual trading floors. Their discussion of duration and convexity employs only continuously compounded interest rates. Sure, this keeps formulas simple, but it isn't how readers are going to see duration used on the job.
