Emily must battle the greatest evil that has threatened The Midnight Hour. Can she keep its magic from leaking into the real world? They must have come from under beds, out of mirrors, up from caves, and down from attics, all out of the darkness and into the moonlight. They were the Night Folk, and this was their world. Now that Emily knows that her blood ties her to The Midnight Hour, she feels more connected to this frozen pocket of time than ever. But not only does she have to come to terms with her new identity as a Pooka, her parents also had to go and have another baby. And how weird is that? Life is feeling frustrating from all angles... But when Emily begins to encounter strange happenings within The Midnight Hour, her worst fears are confirmed: there is a hole in the Hour and it is leaking magic. Whoever is going through it is making the tear worse and worse, posing a threat to the survival of the whole world. With Emily's parents distracted with the new baby, it's up to Emily to find the hole and help fix it.
