Synopsis: From the back cover of the Ace first edition: "In this house, memories shift like sand in a tide." As a child, Dierdre MacCallum remembered her great-grandmother Bridget's house in New York's Washington Square as a magical place - with mahogany walls, antique furniture, and sedate tea parties. But when Dierdre is summoned to the matriarch's side to settle her affairs, she senses something strange about the house, a feeling triggered by an old set of French doors in the sunroom. She pulls back their heavy curtains, opens them to the sunlight... And finds a doorway to the past - seventy-two years ago. There Dierdre will meet Grandmum as a young woman. She will find love with Noah, a man destined to die before she is born. And she will find great danger as she uncovers Bridget's darkest secret - her involvement with the infamously sinister Aleister Crowley, whose dabblings in the powers of darkness promise destruction for the MacCallum clan. Now Dierdre must find a way to set things right, and rescue not only her family, but her one true love..."
