Scars of Grace

From the publisher:

The Order of Stoic Grace (the Grace Order), a once-great chivalric Dynasty, is dying. The disorder in Northern Europe has left the gates open to invaders from the East; bandits from the outskirts of Slovakia aligned with their rising Hillkyn lizard folk, unified under the banner of the Falcon’s Talon. Once a global force for unification, the remnants of the Grace Order now rely on clandestine messages to summon each other in times of need. When Justina Waldron is ambushed on a trail to the Hungarian Empire, the extent of the Falcon’s grip becomes an horrific revelation.
