The birthstone chronciles

Twelve teens. Twelve birthstones. One ancient war reborn. Liana Harrington always thought she was an ordinary girl — until the night her Garnet Stone blazed to life and a mythical guardian rose to protect her. Across the world, others awaken to their own powers: a storm-caller with the Diamond, a healer with the Pearl, a shadow-walker with the Ruby, and more. One by one, twelve are chosen, each bound to a stone tied to the months of their birth. But their awakening has drawn the gaze of Nythros — an ancient enemy who commands nightmares made flesh. From Gem Reavers to Abyssal Devourers, she summons monstrous legions to shatter the new generation of stone bearers before they can unite. Thrust into a battle that spans myth and reality, the twelve must learn to trust each other, their guardians, and the stones they wield. If they fail, the shadows Nythros commands will swallow the world. The circle is complete. The war has begun.
