The Proof (Unabridged‪)‬

Shrouded in mystery, a precious relic known as Il Testamento, or The Proof, circulated among the early Christians for centuries. Before their deaths, its guardians hid it from their adversaries, leaving only a crude map of its location.

For centuries, it lay in darkness. Until now. Reports of its existence have resurfaced, inciting an ancient rivalry between a ruthless group that seeks to destroy it, and a secret association that lusts for its power. Summoned to Siena by a grandfather he has never met, Gabriel Dolcini is thrust into a dark maze of danger. And into his divine destiny.
