She thought her life was over, but it hadn't even started. . .

When Margot Delacroix dies at forty years old, she is sent back to earth as a guardian angel - to herself. Renamed Ruth, she is forced by divine mandate to re-experience and record her biggest mistakes and fiercest regrets from the beginning of her life to her untimely death.

Forced from the moment of her birth to witness the cogs of fate and the stuttering engine of free will, Ruth sets out to change the course of her life, and, ultimately, to prevent her premature death. When she realises that the reasons behind her teenage son's descent into drugs and murder lay within her own actions as Margot, she makes a pact with a demon - she will give up her place in Heaven in exchange for the opportunity to save her son from his fate. But the changes she makes result in consequences no one could expect. . .
