After thirteen failed attempts to save her late mother, bookstore owner Mia Lockwood enters a fourteenth time loop with Major Crimes detective Miles Sterling. Thrown back to her mother Diana's youth, Mia discovers that the mysterious tycoon Victor Vaughn is her father and that a hidden SD card may hold the answer to Diana's death.
As Mia and Miles race through a past filled with staged accidents, assassinations, and shifting timelines, they uncover an international organ-trafficking network determined to erase Diana forever. Though Mia cannot change the fate of her parents in her original timeline, the truth carried by Diana's evidence finally brings the criminal empire down. With Miles beside her, Mia learns to release her guilt and discovers that love cannot rewrite the past, but it can give the present a reason to begin again.
