"Grainger marshals his considerable knowledge of the Hellenistic world to make a good case for the unique character of international affairs in the two centuries after the death of Alexander, showing in the process what we can gain by explaining the interactions among the Antigonids, Seleucids, Ptolemies, and Romans in terms of their diplomacy, not simply of their wars ... Students of Hellenistic history who already have a good grasp on the major players, events, and territories will benefit from Grainger’s palpable erudition and range and may find fresh treatments of particular episodes."- Daniel Tober, Fordham University, USA, Bruyn Mawr Classical Review 2018"He [Grainger] does offer valuable insight into international relations between the great powers of the Hellenistic world."- Carol J. King, Memorial University, Mouseion: Journal of the Classical Association of Canada
