Walls are a very hot-button issue right now and as Frye points out near the end of the book, if you call it a fence there will be less outrage. Frye doesn't just give you a history of walls (from Sumeria, to the various Chinese walls,Hadrian and more) he infuses a dry sense of humour and wit to the proceedings. The book is lively, unabashedly thought provoking, and downright funny. The end comes too quickly, but not before Frye notes the growth industry in walls around the world in the past 20 years, a fact not often mentioned, before Trump jumped into the fray.
