The book is written by White's standpoint and covers non-g3 set-ups: 1.c4 e5 2.Nc3 Nf6 3.Nc3 Nc6 4.e3 as a main weapon and 4.d3 as an alternative. Some notable exceptions are 1.c4 e5 2.Nc3 d6 3.g3, although 3.Nf3 and 3.d4 is also analysed. The book goes beyond a straightforward repertoire, and covers different approaches. Thus it should serve players with both colours.
