The first of many sequels to 1632 and 1633, this book focuses more on the theological-political impact of the Ring of Fire. The newly formed United States of Europe sends a delegation to Venice. This leads, more or less on purpose, to links with the Vatican and involvement in the trial of Galileo. It is a decent read reading, but there is much less action than in 1632 and 1633. Overall, this book is nowhere near as much fun as the first two.
