The Shadowbound Oath

Aurelia Vale has spent her quiet life believing she is ordinary - until the night her birthday awakens a power that should not exist. Marked by a glowing sigil and hunted by creatures older than the sun, she becomes the center of a prophecy every kingdom fears.

And watching her from the edge of reality is Kael Draven - an immortal guardian forged from shadow, bound to Aurelia by an oath sealed before her first breath. He is feared across realms, cursed beyond redemption, and devoted to only one soul: hers.

When an ancient court of wraiths rises to claim Aurelia and a political heir sets his sights on her, alliances fracture, secrets unravel, and the thin boundary between realms begins to decay.
To survive, Aurelia must decide whom to trust - the prince who offers safety, or the shadow-born protector who would tear the world apart to keep her alive.

But destiny is not gentle.
And love, in the hands of the wrong creature, can be catastrophic.

A war of realms is coming.
A girl with forbidden power stands at its center.
And the darkest being alive may be the only one who can save her - or doom her.
