Dark Over Acadia — Anne Talmage

Diana Latham came more than a thousand miles to Devereau House ... to find her friend Lucy Devereau struck down by a terrible accident, imprisoned in her bed by paralysis that denied her movement, or even speech. But was it an accident? Or was it a horrible plot? Lucy's family seemed to accept the first, and when Diana questioned other possibilities, they refused to listen. But the Devereau family carried a dark curse, one that they could not keep hidden; someone... or something ... seemed determined to strike them down. Soon Diana was drawn into the maelstrom of building terror... and it seemed as though her only escape would be through death!
