... riveting ... deftly explores the test of wills between the French emperor and Roman Catholic pontiff in the aftermath of the French Revolution and in the midst of the Napoleonic Wars ... important and wonderfully written.
Caiani relates this dramatic story in telling detail but never loses sight of the broader picture, and uses his archival discoveries to excellent effect. The result is both an exciting narrative and a fine work of scholarship, shedding new light on Napoleonic history and that of the modern Catholic Church. In particular, he pinpoints Napoleon’s worst aspects ... the book’s real originality lies not in exposing Napoleon’s flaws but in bringing his neglected nemesis, Pius VII, out of the shadows.
