Query: a history book for those serious about history

Colin Platt gives an excellent, IN-DEPTH review of scholarship surrounding the impact of the Black Death on late-medieval England, full of original contributions to the field. His chapters are well thought-out and well documented. Some, especially the chapters on church art, are very moving; others, such as the chapter on widows made wealthy by the plague, will force the reader to reconsider their views on literature contemporary to the plague (and here I am thinking of Chaucer's "Wife of Bath's Tale" in particular). If you're looking for stories of gruesome death, well, perhaps this is not the first place to look (although there's still plenty of that here). If, on the other hand, you're looking for a more in-depth look at the plague and what it did to the societies it infected, here's the place to come when you've tired of the gruesome bits.
