Willa has never known her father. In fact, her mother has refused to tell the eight-year-old anything at all about him. Willa dreams about what he might look like and who he might be. She often asks herself why her hair, which is "afro-crinkly", and her skin, which is dark, are so different from her mother’s brown hair and pale skin. A substitute teacher’s request that the class draw pictures of their dads for a Father’s Day card launches Willa on an odyssey to discover the truth. Her head filled with fantasies of kings and princesses, Willa gathers the clues and, with the help of her good friend Marina, begins the alternately amusing and touching search for her father.
