I am thrilled to finally share the news many of you have been waiting for:
My upcoming dark romantasy novel, Mine Eternal, is officially on its way.
This book began the moment one character refused to let me go.
I fell in love with Silas long before this story was ever written—the big, burly demon whose birthright was denied and who spent centuries forced to serve the very Demon Lord meant to kneel before him. At the conclusion of Inevitably Mine, the magic of the realm finally judged his heart and history and deemed him worthy, granting him the crown of the Demon Realm at last.
But what captivated me most wasn’t his strength or his scars.
It was his contradictions.
Silas is tough and gruff, every inch the warrior king… yet he carries an unexpected sweetness, a fierce loyalty, and a moral center no one would ever expect from a demon. A gentleness he hides even from himself—until the one soul destined for him sets it free.
Mine Eternal is the story of what happens when he finally meets her.

Why This Book Matters
Mine Eternal is a story about belonging—
finding home in another soul when you’ve never belonged anywhere.
It’s about fire, fate, fear, and a dangerous, beautiful love powerful enough to shake realms.
In fire and fate,
Kate Oleander
