Like some other reviewers I found the writing so dreary at first that I contemplated stopping reading it. However I persevered and the writing improved - or maybe I just got used to it. Anyway, I was rewarded with a fascinating middle section of the book which covers such topics as slave making, army ants, honeypot ants, invader species, colony structure. However, the final few chapters seemed aimed at biologists more than natural historians. For a while I found the discussion on genetics interesting but soon found it hard work.
Overall, it seems a very approachable book. All the chapters are short and there are numerous colour photos, though (at up to 8 per page) some were so small they seem of little value. I think most people will get something from reading the book but it is rather variable in its interest and the quality of its writing
