A YA fantasy duology in which two sisters have grown up imprisoned in a fortress surrounded by a magical hedge that won't let anyone in or out, until the day a stranger arrives. 

Zuhra and Inara have grown up in the Citadel of the Paladins, an abandoned fortress where legendary, magical warriors once lived before disappearing from the world—including their Paladin father the night Inara was born.

On that same night, a massive, magical hedge grew and imprisoned them within the citadel. Inara inherited their father’s Paladin power; her eyes glow blue and she is able to make plants grow at unbelievable rates, but she has been trapped in her own mind because of a “roar” that drowns everything else out—leaving Zuhra virtually alone with their emotionally broken human mother.

For 15 years they have lived, trapped in the citadel, with little contact with the outside world…until the day a stranger passes through the hedge, and everything changes.
