Almost a year after waking to find himself in twentieth-century New York, fifth-century Celt Ciarán Donnelly has finally returned to his childhood home, but Ireland is nothing like he remembers it. The realization is overwhelming and taking a toll on his relationship with archaeologist Caitlin O’Connell as well. Keeping his secret from her has been no easy task. Due to some quick thinking on the part of her Uncle Mike, however, Ciarán has managed to conceal the fact that he and the Celt that mysteriously disappeared from a local museum the previous year are one in the same.
