I think this book is excellent.
Robertson starts the book of well with his introduction, and then the first few chapters of the book focus oh Marcus's childhood and the influence of various people, such as his mother, father, grandfather, his adoptive grandfather, Hadrian, his adoptive farther, Antoninus Pius, and his many tutors. This first bit gives a great overview of the world Marcus grew up in and the qualities he wanted to emulate and the ones he wanted to avoid.
Further on in the book, we see Marcus become emperor of Rome, while at the same time making the Senate make his adoptive brother, Lucius Verus, Co-emperor. We see their relationship grow and how they balanced eachother out in a way. We see the various different qualities that they both possessed, the world in which the both faced, and sometimes the conflict that arose between them.
Then we move onto the multiple Wars that Marcus had to face during his reign. Starting with the Parthians, and then Germaninc tribes, we see how Lucius Verus was during this time, up until his untimely death. Then we move on to all his other wars in Europe. Near the end though, it becomes focused on the civil war that Marcus faced due to Avidius Cassius in the East. We see how this ends and the results of it.
We end the book with Marcus' returning to the Danube frontier to fight another war. His death comes in around this time and we see him try and prepare for the sole reign of his son, Commodus.
The writing structure was straightforward and enjoyable to read, Robertson constantly made links to Marcus Aurelius Meditations, giving us a greater insight to Marcus himself and his views on the world and how he dealt with scenarios, like the constant loss of those close to him, or the constant wars he faced.
Overall, this is a well structured, enjoyable quick read that is full of knowledge and is a great book on the life of Marcus Aurelius. I can find no critique with it and would recommend anyone Intrested in such history read it.
