Warriors of Light Series
An alternative supernatural world based on our real world with real places. Book 1 is centred around the port and naval town of Plymouth. But there are several ties to Europe including the mysterious organisation of Warriors of Light who battle the forces of Evil to keep humanity safe from Demons who have their base in Romania, and later ties to Jerusalem the seat of "The Book' based religions.
I started writing this before I read Cassandra Clares Shadow Hunters but there are certain similarities in the worlds in that they are urban fantasies about demon hunters, angels and demons except this is set in Europe while the Shadowhunter series is set mostly in America.
