A monk banished for sins he didn't commit. A secret mission that could redeem him-or condemn him utterly.

In 1458 Piedmont, novice monk Andreas de Bonomo's promising future shatters when false accusations exile him from his Benedictine order. His abbot, aware of the injustice, offers a clandestine path to absolution: infiltrate a burgeoning heretical sect in the rugged Alpine valleys.

Armed with his wits and language skills, Andreas arrives as a traveling scribe, offering to chronicle the history of the mountain folk. Yet, as he delves deeper into the lives of the Vallenses-a community committed to the Bible-he finds not fire-breathing devils, but a people of unwavering faith and conviction, whose understanding of scripture challenges everything he's ever known.

Caught between his sworn duty to the Church and the compelling truth he uncovers, Andreas must decide where his loyalties truly lie. Will he expose these heretics or risk everything to protect a faith more ancient and pure than he ever imagined?

In a world on the cusp of seismic change, one man's search for truth could ignite a fire that reshapes history.
