Grace Carter's mother, GG, is everything teenage Grace is not. GG is glamorous and breezy, while Grace is a low-key dreamer. The two may share a name, but that's where the similarities stop. With nothing much in common, the two hardly speak to each other. Then one day GG is just... gone. Cameras descend on their house, news shows speculate about what might have happened, and Grace's family struggles to find a new rhythm as they wait for answers. While the authorities begin to unravel the mystery behind GG's disappearance, Grace finds herself learning secrets from her mother's long-lost past. The more Grace learns, the more she wonders. Did she ever really know her mother? Was GG abducted... or did she leave? And if she left, why? A suspenseful and sensitive exploration of the gravitational force between mothers and daughters.
