This elementary introduction to group theory is supposed to be unique in its use of graphs to represent groups (Cayley diagrams), which would be an interesting and fresh approach to teaching group theory. But no, the authors don't deliver what they promised. It's the same old group theory, with a few Cayley diagrams thrown in here and there. Of the few Cayley diagrams that actually appear, many are so very trivial that they just seem stupid (C_n, Z, etc.). In fact there are only two nontrivial Cayley diagrams in the whole book: the quaternion group and the icosahedral group (last page).
