" I first read Costain's four-volume history of the Plantagenet family back when I was twelve or thirteen--- long, long ago. The books have long ago dropped out of sight--- popular history published first more than half a century ago. And that's a pity. I can't say that they're academic history, or that Costain's interpretations of England from the 1140s to 1485 have held up. But these are the books that introduced me to Anglo-Norman England and to a host of figures (Henry and Eleanor, the over-maligned John, Edward I, the over-praised Henry V, the tragic Richard III) I went on to read about in other, more academic works. I think the Costain books still work as an introduction, and I very much think they're good reads. "
