It has long been rumoured that a sixteenth-century monk called Eisenreich out-Machiavellied Machiavelli, writing a masterplan for the Church to achieve world domination. So dangerous was the text that the Pope had to kill Eisenreich to suppress it. But when the bullet-riddled body of a young girl is found in the mid-West and "Eisenreich" is her dying word, it becomes terrifyingly clear that not only is the document real, but someone is planning to use it. Sarah Trent, a US agent, and Xander Jaspers, a Columbia University professor, race to find this manuscript, but neither fully understand the danger they're confronting as it has fallen into the hands of a cabal who intend to use it to rip society apart, and create a new world order.
