From publisher blurb:
Brother Hoffman is far and away the most talented inventor to have passed through the ranks of The Order. As a Prior Artifex, he was without equal. His devices have aided countless hieromonks to overcome supernatural foes that would otherwise have bested them.
News, therefore, of a lost device – of a machine Hoffman was working on when his mind failed him – is of the utmost importance. Agents are dispatched at once and charged with locating the plans to Hoffman’s last great invention…
A complete adventure for Deus Vult.
