The Outlands Demon - The Devil's Outlands, #2

Jump into the world of the Devil's Outlands, where time travel, magic, and enemies-to-lovers romance collide. The demon king Zor'imuth is no more, destroyed by the British werewolf Nathaniel Fortescue and his fated mate, the American Kylie Drummond. Years have passed in the modern world. The threat of the Outlands is over, or so it seems. Until the daughter of Nathaniel and Kylie comes of age. Zaen'imuth, son of the demon king, has sensed Charlotte Fortescue, though he can't find her.
He will cross worlds and time itself to hunt down the woman he craves. But something strange is happening to the demon, and his desire to take an innocent mortal for his slave has transformed into something far more dangerous for them both. The Outlands Demon is the second book in The Devil's Outlands series of paranormal romance.
