This book is a welcome addition to the textbook literature in statistical mechanics. It does not (and probably does not pretend to) replace some of the standard texts that cover the field more broadly, but it certainly supplements them with modern material presented very well. The author has managed to make this material accessible to students at the high undergraduate and beginning graduate level without requiring a tremendous amount of sophisticated antecedents. The book gives the student a real flavor of the issues in statistical mechanics as currently seen in the physical chemistry community.
