This highly specialized book is interesting not only because of its important subject matter but also because of its egocentric perspective. The majority of the book provides a nearly exhaustive retrospective of the authors’ many contributions to the shallow‐flow theory of granular avalanches, and it also critiques contributions by others. Indeed, some readers (including this reviewer) might be dismayed to find their own contributions critiqued inaccurately! This brief review will not attempt to correct inaccuracies, however, but will emphasize the book’s main features.
