Much like the Hannibal biography I'd previously read, this book provides a solid overview of one of the most important figures in history. I didn't know too much about Alexander and his campaigns before reading it, so the book worked very well in providing all the most important events.
Jacob Abbott does have a tendency to repeatedly condemn acts of brutality that were commonplace during such times. As such, it can get slightly irritating after a while. Still an enjoyable read though (plus it's free on kindle!).
