For one, Scullard is so inclusive and thus hard to enlarge upon. On the other hand, where he finds conflicting opinion he points it out in an endnote, and most of the time I would have to go to JSTOR to get more information, and most of the members of the book chat do not have access to that organization and it articles.
So my recommendation is to really keep and eye on the endnotes. I keep a little bookmark in place to make it easier to find them.
I know that there are time constraints for our readers. I would say that as a must, in PART I, read Chapters V and VI on the conflicts between the social orders, the constitution, the organization of Italy, and the attitude of Rome towards its regional adversaries. Without it, the amazing rise of Rome may not be fully understood. Then moving on to PART II, Rome and Carthage, there will be a more straightforward and faster to read narrative.
