Brenna Morgan and the Iron Key

When sixteen year-old Brenna Morgan arrived in Ireland with her travel-writer mother she had expected the usual-a couple of months in a country that wasn't her home. What she hadn't anticipated was making a promise to a dying faerie who saves her life. Armed with only her wits and a strange iron key given to her by the faerie, Brenna is pulled into a world where myth and legend cross all too often into reality, in search for a child hidden away in their world. Knowing nothing of the faerie realm, she is aided in her search by her new found friend Patrick and a reluctant faerie named Roibhilin with a grudge against humans. But the more she uncovers the more she realizes that not all is as it seems, that danger comes in the most unassuming of guises, and that the child she is sworn to protect could destroy not only the faerie world but her own as well.
