Huber and Ronchetti* *have provided us with a long-awaited second edition of *Robust Statistics*. There is little need to mention the impact Huber has had in this area, which is further passed on to us via great texts such as the one under review. Looking back to the first edition, one can only conclude that the present one contains even more lucid explanation and concise presentation of theoretical ideas and concepts.

The book is technical but quite understandable, with clear mathematical exposition leaving little room for confusion. Numerous illustrations are presented to explain theoretical concepts further. Generally, the authors do not skip steps when it comes to proofs (some steps in easier-generally known concepts are skipped, but I would not count that as a negative aspect) and, as mentioned before, the explanations are narrative and clear. There is a “warm*-*up” section at the beginning of each chapter.

The authors have added four new chapters, namely: *Robust tests, Breakdown point, Small sample asymptotics, *and *Bayesian robustness.* There have also been additions to the existing (first edition) chapters. The bibliography has also been updated.

Even though there are no exercises, I could see this book on a course list for graduate level courses. It would be of great use to researchers and practitioners who apply robust methods in their daily work. Overall, this is an excellent addition to the statistics library shelf.

Ita Cirovic Donev holds a Masters degree in statistics from Rice University. Her main research areas are in mathematical finance; more precisely, statistical methods for credit and market risk. Apart from the academic work she does statistical consulting work for financial institutions in the area of risk

management.
