Get swept back to Partholon in this fan-favourite series by No.1 New York Times bestselling fantasy author P.C. Cast.

I was marked from birth as belonging to the Goddess Epona - but that didn't make my life easy. Because of my "blessings," I was set apart, worshipped, unable to make real connections with others. Then came the Feeling, and with it a glimpse of my destiny. It led me to the MacCallan castle of legend, deserted since the terrible Fomorian war.
I followed the wordless call to breathe new life into a place long dead, but I didn't realise there were dark remnants of the war lingering in the nearby forest - victims and survivors who remained hidden. Others marked as different, powerful. Feared.
My choice was now twofold. I could keep to the happiness and safety of my newfound home, or I could choose a path that led to something more terrible, more dangerous, more thrilling than anything I'd ever expected.
And in that future, I might never be alone again...
