The Iron Bells

The year is 64 A.D. -- though now A.D. stands for Anno Daemonii.
Demons have crossed a gate into our world, taking the reins of power
from humanity. A new Inquisition has begun, determined to root out any
who stand against the new world order. The holy sites on earth have
been destroyed -- Jerasulem first, then the Vatican, then Mecca -- and
what resistance remains is ruthlessly crushed. Amaranth is a fighter
in the resistance cell based in London. Dham is a Ringer, one of the
few people left able to ring the remaining sets of blessed hand bells
that have power over demons. When Amaranth discovers that her best
friend has been possessed by a demon and is going to be used in the
Resistance's final, desperate mission, she asks Dham for his help in
saving her friend. With the Inquisition closing in and betrayal
threatening from inside the Resistance itself, Amaranth, Dham, and the
demon -- along with Catriona, a new, highly-skilled, highly-blonde
bell-ringer -- decide to head to Rome and the ruins of Vatican City,
hoping to find a way to stem the tide of demonic possessions and close
the gate.
