Fred Anderson's Crucible of War is a great book on the subject, one of my favorites. He links the War in America to the wars across Europe, Africa, and India, in a way which I dont think many other authors have done. So it gives you the overview of everything which happened during the war as well as a closer examination of important battles and events, such as the Plains of Abraham or Braddock's Campaign. Anderson's The War that Made America is a shorter version of that story, if you arnt into doorstops, but I havnt read that volume.
