The Horned Women by Christy Matheson

All that American folklorist, Maura, wanted from her contentious divorce was custody of her two young children–and an Irish castle. She ended up with more than she bargained for, including her ex’s teenaged kids and now…twelve horned women in her living room. The Horned Women demand tea, then cake...and then blood. Maura is determined to keep her otherworldly visitors away from her children, but is a stepmother’s love enough to save the grumpy teens?
