LEVER TEMPLAR (coming soon)
"I'll be getting Advanced Reader Copies (ARCs) out soon." —Matt
As the crusader era ends, Templar Sergeant Brim Hastings must free his
imprisoned brethren by surrendering the heretical scroll that has enabled their two-hundred-year leverage over the Roman
Catholic Church. After escaping his order's persecution, and having the role of savior thrust upon him, he and
Cypriot apprentice tanner Shayla Kostas discover the boundaries between good and evil are not where they'd thought.
Seven centuries later, Rick Lambert's investigation into Christian priest abductions in Iraq
grows in scope after he's given a cryptic Roman gaming stone. As he learns of the motive for recent Templar preceptory
demolitions throughout France, he and his team must prevent religious extremists from shattering Christianity by winning
the race to rediscover the Vectis Templi—the Lever of the Temple.
WHISPER ANGELIC (in work)
While a young acolyte at the Council of Nicaea in AD 325, Dami Romanos
witnesses the beginning of Christianity's civil war between the Trinitarians and those supporting Arius, the excommunicated
presbyter of Alexandria. During his nearly six-decade rise to become Bishop Damasus of Rome and Vicar of Christ, he must
continually protect orthodoxy from heresy. Despite their ultimate defeat at the Council of Constantinople in AD 381, the Arian
faction promises a return.
Over sixteen hundred years later, all of Rome anticipates Vatican III, the first ecumenical council
in over five decades. The most influential cardinals of the Congregation for the Doctrine of the Faith begin to succumb to
delirium, dying only after screaming a long-forgotten enemy's motto—The Father is greater. Rick Lambert and the
Castellum One team must find the source of the outbreak, and a cure, before it spreads to world leaders.
Matt Gianni is the author of dual timeline historical fiction / contemporary thriller novels built around his Castellum One
team, a covert investigations unit financed by the Vatican and run by elements of the US Intelligence Community. LEVER TEMPLAR, the
first in the series, has been described by readers as "THE DA VINCI CODE meets NATIONAL TREASURE." After a long career in
aeronautical engineering and flight instruction, writing countless airplane flight manuals for Boeing and instructional articles for
flying magazines, he began writing fiction in 2013. When not writing, or learning of obscure historical oddities, he enjoys weight
lifting and salsa dancing on Seattle's east side.
