Changing World Order is one of my favorite books, right behind Nik's "Layered Money". Ray presents a simple and logical explanation of nations losing their dominance on a global stage. My only critique is the final chapter where Ray intentionally is ambiguous about his viewpoints on the future. The ambiguity of the last chapter could have been omitted.
"When Money Does" is more of a narrative of individuals who were directly impacted by hyperinflation (e.g stories of breadlines developing, life savings being wiped out, etc). It's an interesting read and highlights actions that individuals take to preserve their wealth and wellbeing (some are successful, others are not).
