From the reviews: H. Kurzweil and B. Stellmacher The Theory of Finite Groups An Introduction "An exciting and refreshing contribution to an area in which challenges continue to flourish and to captivate the viewer. The text serves as a springboard for deeper study in many directions. One who completes this text not only gains an appreciation of both the depth and the breadth of the theory of finite groups, but also witnesses the evolutionary development of concepts that form a basis for current investigations." -MATHEMATICAL REVIEWS "The book under review is incontrovertible proof that the theory of finite groups per se is alive and well too. ... is also a marvelous treatment of a large chunk of what is going on today. ... There are a lot of nice exercises, the scholarship is phenomenally thorough ... . The entire presentation is quite elegant. ... If I, personally, should wish to learn a lot of serious finite group theory I'd go with this book ... ." (Michael Berg, MathDL The MAA Mathematical Sciences Digital Library, July, 2004) "This book is a tour de force. In the space of 387 pages, it takes the reader from the definition of a group ... developing and illustrating many of the deepest techniques which have been deployed in the analysis of finite simple groups. ... It is also fascinating reading for anyone interested in getting an excellent introduction to a wide spectrum of ideas and methods, many originating in Thompson's N-group papers, which played a critical role in the original proof of the classification theorem." (Ronald Solomon, SIAM Reviews, Vol. 47 (4), 2005) "This is the English translation of the book 'Theorie der endlichen Gruppen' (1998), which has met warmest reception and has been reviewed enthusiastically. ... a book which gives a deep insight into the modern theory of finite groups." (G.Kowol, Monatshefte fur Mathematik, Vol. 146 (2), 2005) "This valuable text is a welcome translation of the highly-regarded German version ... . As a whole this book is carefully constructed and shows all the hallmarks of having been honed over a number of years so that the necessary concepts are all in place when needed, and the development unfolds in a fluent manner. ... This is a book which every serious student of finite groups will want to own, and one which makes a highly significant contribution to the discipline." (Robert T. Curtis, The Mathematical Gazette, Vol. 89 (515), 2005)
