Keeper of Scales: The Trianid #1

A princess with a secret. An ancient evil rising. A kingdom caught in the balance.

Alyen, crown princess of Dúramair, has trained her whole life to be queen. She’s kept her faerie Sight a secret, trusting that the Keeper of Scales will find an apprentice soon—for surely one other candidate can be found. But when news comes from the north of dark magic returning to Dúramair, Alyen is forced to make the hardest decision of her life. A decision that could determine the fate of her kingdom.
Soon Alyen and her friends find that they are the last hope for Dúramair’s victory in a looming war. Forced to choose between love and duty, Alyen struggles to master her growing powers, knowing that if she fails, she risks destroying everything and everyone she loves.

Keeper of Scales is a young adult fantasy with adult appeal, featuring medieval settings, slow-burn romance, elemental magic, and a strong female lead.
