About the book, from the publisher:
Killing a teacher in the school cafeteria lands Teagan, Finn, and Abby's family in trouble with the law. Mamieo calls in a young half-Traveler half-Scottish lawyer, Seamus McGillahee, telling him the Almighty has spoken to her about a great mending and tending to be done in Mag Mell.Visit Kersten Hamilton's website.
Seamus and Tea get along well until he finds out that she is sĂdhe—but that is just the beginning of the unsettling things he encounters as he joins the battle against goblin kind. The Wylltsons try to carry on with their lives, but Aiden is badly scared by a new song that is stuck to him. More goblins have snuck into the city, and Ms. Skinner is still causing trouble for Teagan and her family. Meanwhile, Tea and Finn’s relationship is heating up, but he is still bound by the curse of the Mac Cumhaill to fight goblins his entire life, and by blood she is one of them. Nonetheless, at night Teagan leaves her flesh and bones behind and hunts goblins across Chicago with Finn and the phookah Gil.
Then the gateway to Mag Mell opens, and the Wylltsons find themselves caught in a trap. Mab and Fear Doirich are back together again, and they are angry. As her loved ones begin to die, Teagan realizes that she must return to Mag Mell and fight to set things right and save those who remain. . . . But can she destroy the Dark Man and his minions and release Finn from his curse before it's too late?
