Books like Shadows Kiss (Beeler) by Joan Hohl

Court seducer La Belle Coeur has met her match in Tristan, a Knight of the Round Table unafraid of blood--or lust. Joining together to combat a werewolf wizard and sworn enemy of Arthur, they must put their lives on the line while coming to grips with the rising heat between them.

When a young bride wakes to find herself entangled in a dangerous plot, she finds an unlikely ally in a mysterious English lord. Their forbidden romance turns them into passionate outlaws.

Old Ms. McMartin is definitely dead. Now her crumbling Victorian mansion lies vacant. When eleven-year-old Olive and her dippy mathematician parents move in, she knows there's something odd about the place--not least the walls covered in strange antique paintings. But when Olive finds a pair of old spectacles in a dusty drawer, she discovers the most peculiar thing yet: She can travel inside these paintings to a world that's strangely quiet . . . and eerily like her own. Yet Elsewhere harbors dark secrets--and Morton, an undersized boy with an outsize temper. As she and Morton form an uneasy alliance, Olive finds herself ensnared in a plan darker and more dangerous than she could have imagined, confronting a power that wants to be rid of her by any means necessary. It's up to Olive to save the house from the dark shadows, before the lights go out for good.
