17-year-old Becca has spent her whole life protecting her brother -- from their father leaving and from the people who say the voices in his head are unnatural. When two strangers appear with apparent answers to Ryland's "problem" and details about a school in Ireland where Ryland will not only fit in, but prosper, Becca is up in arms.

She reluctantly agrees to join Ryland on his journey and what they find at St. Brigid's is a world beyond their imagination. Little by little they piece together information about their family's heritage and the legend of the Holder race that decrees Ryland is the one they've been waiting for--but, they are all, especially Becca, in for a surprise that will change what they thought they knew about themselves and their kind.
