From bestselling author E. E. Star comes a brand-new historical fantasy prepared to sweep you off your feet.

Outlander meets Irish mythology meets The Wolf King in this dark, historical fantasy romance about rebellion, destiny, and the strength of love and loyalty against the forces of evil.

The Emerald Oath is Book 1 in the Oathbound prequel series, set in the world of the Warriors of the Raven Queen. This new trilogy can be enjoyed independently of the main series.

In 1798, Ireland stood on the edge of open rebellion.

As unrest spreads across the country and the grip of British rule tightens, a darker threat begins to stir beneath the bloodshed. The Emerald Oath, an ancient vow forged before mortals came to rule Ireland, guards a secret tied to a darkness now beginning to seep back into the world.

Bound together long before they were born, a group of allies are drawn toward the same dark truth. As violence spreads and the line between fate and choice begins to blur, they must decide who to trust, what they are willing to sacrifice, and whether the bonds they have forged through friendship and love can survive what is coming.

Because if they fail, Ireland will have far more to fear than rebellion. A darkness is rising, and it will not stop until the land is reclaimed by forces seeking to hold unimaginable power.

The Emerald Oath is a sweeping, high-stakes historical fantasy set against the unrest of 1798 Ireland and Scotland. During this time, Ireland was reeling beneath the violence of rebellion and Crown retaliation, while communities throughout Ireland and the Scottish Highlands endured the brutal weight of colonial violence, political suppression, and cultural erasure.

This story was born from equal parts history, mythology, and heart. Within these pages, real figures who once walked this earth stand beside beings pulled from the oldest corners of Irish legend. Some details have been shaped to serve the story, but never carelessly, and never without deep respect for the truths, people, and cultures that inspired them.

Within these pages, you’ll encounter elements including: colonial violence, cultural suppression, political conflict, war, death, grief, loss of family, domestic abuse, pregnancy loss, wrongful execution, torture, physical violence, and consensual sexual activities shown on page.
