She was never meant to cross worlds. He was never meant to betray his own.

For years, Addie Howell has dismissed the nightmares of a blue-eyed owl and a shadowed forest as nothing more than anxiety.

Until one night, the dreams pull her into Threllwood--a kingdom where ancient magic stands little chance against a devouring darkness, and a ruthless queen holds Addie's fate in her hands.

Her only hope of surviving is the Queen's commander.

Gwilym Noctura is feared throughout the realm for good reason. Deadly, fiercely loyal, and bound by unbreakable oaths, Will wants nothing to do with the mysterious mortal who has appeared in his world.

Until Addie unleashes a power no one expected.

Now hunted for the magic buried inside her, Addie has no choice but to trust the one man sworn to serve the queen determined to claim her. But as monsters gather, secrets unravel, and an undeniable attraction grows between them, Will is forced to choose between the duty he's sworn to uphold...and the woman who could change the fate of his world.

Because the greatest threat to the kingdom may not be the darkness closing in.

It may be the choices they're willing to make for each other.

Perfect for readers who love romantasy, enemies-to-lovers tension, morally gray heroes, hidden powers, magical kingdoms, forced proximity, fated mates, and slow-burn romance.
