Alone in Scotland on Christmas Eve, Vilek thinks his luck has turned when he finds a castle on the moors. Seeing candles and mistletoe in every window, he assumes it's a friendly place, filled with holiday spirit. Unfortunately, the sole occupant, handsome but grumpy Leland Reid, is less than welcoming.
Leland's ancestral home is the site of a rare portal that once a year can allow demons to pass from their world to ours. As a warrior witch, Leland's duty is to keep the portal closed and defend the castle from beasts that wish to set their evil kin loose on our world.
The last thing Leland wants is to entertain a guest, yet he has little choice but to invite Vilek in. He doesn't realize that Vilek is no stranger to magic and is fighting demons of his own. Only together can they hope to survive Christmas Eve and find a love neither expected.
