The Changeling Soldier (Annwyn)

Her time in the mortal world is running out...
After fleeing Annwyn three centuries ago, Ella built a life in the mortal world making gowns for European royalty and playing in mortal intrigues. Now those Courts are long gone, and she dresses Hollywood starlets. Mortals come and go, but Ella always ends up alone. She longs for the home she left behind.

He's been dreaming of the coming battle all his life...
Isaac Norton is a returned soldier. Now home, he's restless and his recurring dream is becoming more frequent: he's fighting on a snow-covered field stained with blue blood. When he sees Ella, he knows she isn't human. And she knows what he is, a changeling.

Ella can give Isaac the answers he needs, but there will be a price to pay: his soul.
