LOVE’S MAGIC by Traci E. Hall
Celestia Montehue has inherited special healing powers from the maternal line of her family. It comes with a glitch. The year is 1192, witch hunting abounds in England and she can only marry for love or risk losing her gifts. Nicholas Le Blanc is a soul-sick Crusader who escapes from his captivity in Tripoli. He wants redemption and forgiveness from God for losing the sacred relic of Saint James the Apostle. And the other matter of murder, as well.
Forced to marry and move to Falcon Keep, which is haunted by Nicholas’ mother, they must learn to love one another before their family’s curses doom them for eternity.
