This is a truly excellent and beautiful textbook. Very well written and organized with everything laid out and explained very clearly and precisely in what is generally considered a technically formidable subject, and one that can very easily become messy and confusing to those attempting to learn it. However, the authors carefully present all the building blocks of supergravity theories and in a sense "decode" it all for you. As you progress through the chapters, you see it all coming together before your eyes and the basic universal structure of supergravity becomes apparent. The material in the first half of the book alone is worth the asking price: excellent treatments of field theory, Clifford algebras and spinors, Rarita-Schwinger fields, group/gauge symmetries, basic supersymmetry and introductions to super Yang-Mills and Wess-Zumino models, differential geometry and forms, standard Einstein gravity, tetrads and spin connections, gravity and fermions, etc., etc. More advanced chapters will take you increasingly deeper into supergravity and introduce you to everything from Kahler manifolds to the celebrated ADS/CFT correspondence. Good problems and exercises on most pages give you the opportunity to work and play with the technical concepts as they are introduced. A highly recommended text.
