Happiness has moved from the fringe to the mainstream of psychological inquiry in a relatively short time. Scholarly articles and books on hedonic well-being abound. Outside the academy, trade books on happiness are a hot commodity too. So, do we really need yet another book on happiness? Yes, absolutely. Diener (Univ. of Illinois, Urbana-Champaign) almost single-handedly developed the rigorous study of subjective well-being, and his son, Biswas-Diener (Center for Applied Positive Psychology, UK), studies happiness around the globe, gathering data in odd, unusual, and unlikely spots. This fine book covers happiness in broader, more comprehensive ways than its academic and popular-press competitors, and it is written in a clear, accessible style that will appeal to lay audiences as well as scholars and professionals. Indeed, this reviewer believes it to be the best of the bunch. Anecdotes often introduce data and theory, and draw readers into seeing how findings can inform their own lives; at the same time the authors are quick to explain that the pursuit of happiness is best treated as a process and not a destination. Advice on enhancing one's own happiness is literature based, not faddish, and ultimately practical. This book has something for everyone. Summing Up: Highly recommended. All readers. D. S.
