The is a great book. It can be a bit dry at times and it is long but the material it covers is quite unique. It doesn't just cover the ground campaigns fought on New Guinea, New Britain, Guadalcanal and the rest of the Solomon Islands. It has entire sections covering morale, disease, training, medical facilities, terrain, weapons, tactics and logistics.
Amongst these categories it often differentiates between differences between the participants; the American Army, the Marines, Australian militia and regular army, the crack Japanese troops that began the campaign and their lesser replacements. In that regard this book is specialized and probably would not appeal to casual readers of the Pacific War, but to someone who already has a good knowledge of the campaign and is interested in reading a unique perspective on the issues that contributed to the campaign as a whole, the book is invaluable. There are a few minor spelling errors and an insignificant factual error but they do not detract from the superb quality of this book. I did find the epilogue at the end a bit odd and unnecessary.
Nonetheless, this is a wonderful niche book and belongs in the library of every avid historian of this part of the conflict.
