The Darkest Knight by Hildie McQueen

Trapped in a Cursed Realm, Their Love Could Break the Chains—or Seal Their Fate.

Niall MacTavish thought his heroic deeds would earn him peace, but saving a small Scottish village brought him only torment. Trapped for centuries in a sinister realm ruled by an evil wizard, Niall has accepted his grim fate. Bound by a dark curse and haunted by a demon that controls him in his sleep, escape is unthinkable—even when a fierce and beautiful stranger arrives with the power to set him free.
Tammie Lockhart didn’t expect her trip to Scotland to unravel all she’s ever known. Discovering her own untapped powers, she’s dragged into a realm of danger and magic, where she meets the brooding warrior bound by shadows. Niall claims he doesn’t need saving, but Tammie sees through his defenses—and into his heart.
As passion ignites between them, Tammie must confront an impossible choice: risk everything to break the wizard’s curse, or lose the only man who has ever truly touched her soul.

Will their love be the key to defeating the darkness, or will evil claim them both?
