Loved this book!! The Roman empire’s richest citizens are relaxing in their luxurious villas, enjoying the last days of summer. The young engineer Marcus Attilius Primus has just taken charge of the Aqua Augusta, the enormous aqueduct that brings fresh water Bay of Naples. His predecessor has disappeared. Springs are failing for the ﬁrst time in generations. And now there is a crisis on the Augusta’s sixty-mile main line—somewhere to the north of Pompeii, on the slopes of Mount Vesuvius.
