The Dream Thief

The Empire is on the verge of war. 
The ancient enemy has returned and betrayal is thick in the air. 
Eight years after Kalena became a Flyer, she is being sent North with her wing to garrison the mountainous Northern Pass. They are the first line of defense against unknown enemy numbers. 
But what she encounters there, no one could have foreseen and is more dangerous than what the Empire faces to the North.
