A Celtic Vow by Sky Purington

Will a twenty-first century woman and a medieval Irish king find love on the other side of hate?

Constance loathes the monstrous king she’s destined to help and likes the queen she’s supposed to defeat. To that end, she’s determined to travel back in time, finish off the man who should have been her ally and find a way to rally peace with his enemy. Or so she thinks until she arrives in medieval Ireland and learns things might not be what they seem.
Finally free of his nemesis, Aodh, the great Dragon King of the North, wants nothing to do with Constance, the lass who’s supposed to help him save his country. Why would he when she’s aligned with the queen who imprisoned him? Or so he thinks until Constance, who’s on the brink of death, ends up in his arms, and everything changes.

Thrust on a path neither could have foreseen, Aodh and Constance have no choice but to confront a forgotten past. One full of joy and sorrow. Blasphemous secrets. An unthinkable outcome. Most of all, though, a deep love that withstood everything fate threw at them. Can they rediscover it again? Or is their love, no matter how strong it once was, unable to withstand everything trying to stop it now? Darkness so relentless, Ireland faces certain ruin. Find out in the epic conclusion of The MacLomain Series: Irish Roots.
