The past meets the present when American journalist Kayla O'Brien makes her new home in Killaloe, Ireland, called back to her Irish roots. Researching her ancestry as she settles into her new life, it is when she begins that summer attending events with a group that visits historical and spiritual places that Kayla begins to have dreams that mysteriously seem like they are taking place in another time, long ago.

She especially feels drawn to Bael Boru (Brian Boru's fort), an ancient ringfort and historical site long believed to be the ancient lands of the high king of Ireland, and is drawn into the otherworldly sound of the wind through the trees there. Kayla continues to experience a deeper connection to Ireland through music, the sounds of nature, and dreams of the past that start to feel more and more familiar.

As her dreams continue, they start to mirror more and more her waking life. And her new love interest, a publicist for an Irish band, feels strangely familiar too. By the time Kayla's journalistic work takes a surprising and riskier turn to Irish politics and she discovers an Irish relative she did not know she had, she feels a pull that goes far beyond her ancestry search. She begins to wonder: Is there something more to her connection to Ireland than her ancestry?
