Lucy DiCamillo is safely surrounded by her books, music, and art--but none of these reclusive comforts or even the protective efforts of her grandmother, Kitty, can shield her thoughts from the mother she can barely recall. Lucy senses her grandmother holds the key, but Kitty seems as eager to hide the past as Lucy is eager to find it. From the streets of San Francisco and Sacramento to the lush vineyards of the Sonoma Valley, Lucy follows the thread of memory in search of a heritage that seems long-buried with her mother, Ruby.
