What does you in-brain or heart Frannie asks herself this question when, a week before she turns fifteen, her dad dies, leaving her suddenly deprived of the only human being on planet Earth she feels understands her. Frannie struggles to make sense of a world that no longer seems safe. She discovers an elegant wooden box with an inscription: Frances Anne 1000. Inside, Frannie finds one thousand hand-carved and -painted puzzle pieces. She wonders if her father had a premonition of his death and finished her birthday present early. Feeling broken into pieces herself, Frannie slowly puts the puzzle together. But as she works, something remarkable begins to happen: She is catapulted into a foreign landscape suspended in time where she can discover her father as he was B.F.-before Frannie.
