Aether in Bloomington, MN

Seven hundred years after the world ended in fire, the remnants of humanity cling to life amid ruins and superstition.
Countess Ella Wellington was once Yorke's most skilled infiltrator-an elite intelligence officer trained to steal secrets, dismantle threats, and vanish without a trace. Now retired, she's dragged back into conflict when a deadly pagan cult strikes at the heart of her kingdom.
But as Ella pursues their elusive leader across a world haunted by the artifacts of a forgotten age, she unearths a far more terrifying truth-one that could unravel the last threads of order and reveal the true cost of survival.
The war is beginning again... and the key to humanity's future may lie in the hands of the very enemy she was sent to destroy.
