Little, Big (1981)

Smoky Barnable marries into the Drinkwater family at Edgewood, a house whose architecture seems to lead further into the world of faerie. Generations, photographs and the patterns of family life carry the enchantment. Crowley lets you sense a design larger than any one character can see, while keeping love and loss in view. A long, leisurely choice for readers willing to live with uncertainty rather than hurry towards an explanation.
