I've been thinking about this for a while, so what do y'all readers think.

Rise of the Guardians: The Grimm Reaper, Granddaughter of North

Serenity Johnson was always sick when growing up, always bedridden. Her Grandfather would keep her company and keep her in wonder at the world around her.

One day, she loses the fight to stay alive and she is brought before Man in moon, or Manny. Manny makes her the Guardian of life and death.

Years later, on his death bed, Serenity is surprised when Manny brings her Grandfather as the Guardian of Wonder and so Serenity isn't lonely anymore.

What y'all think. Should I do the story.
