Eilis is the quiet, introspective daughter of the Lord of the Oak Castle, and in every way the antithesis of her exuberant twin sister Sibeal. Whereas Sibeal is eager to meet her lover, Lord Berach, for the first time, Eilis is not keen on all the fuss. So the last thing she needs is to be forced to trek through a magical, wintry landscape, and certainly not in the company of the charming but unreliable Cathair.
Yet that is exactly what awaits her three days before Midwinter, for the winter flame will have to be ignited or all will be lost.
