He saved her from certain death, but is he more dangerous – to her heart? In 13th century France, attacked by those carrying out the Papal Inquisition, Magiste Enchantress Chantal Belliveau is thankful for rescue from certain torture and death. But she never expected it to be at the hands of Henri Marchand, one of a powerful pure-blooded line of ancient Magiste, the Zyndevines. Henri holds the key to her survival, but the danger he poses to her heart and soul could turn out to be even more perilous.

Henri is part of Il Resistasse, a handful of powerful Magiste fighting the atrocities the Catholic Church inflicts on their race. Saving Chantal becomes more than a simple rescue — the innocent young woman with half-trained powers enchants him more than he has ever been before. That she enjoys the dark side of pleasure he inflicts makes him question his determination to never give another his heart. Chantal is horrified when Henri invokes an ancient spell, the Possede Puissant. The incantation leaves her little more than his possession.

While she finds herself enjoying his dark and wicked sensual delights, she determines to free herself. Still, the security she finds with Henri encourages her to stay by his side, claiming spell or not. Resentment toward her from Henri's family convinces Chantal she must ultimately break free of Henri's possession. When the Inquisitors attack, Henri convinces Chantal to embark on a journey to a new land, a journey that may well mean the survival of the entire Magiste race but the loss of her freedom forever.
