Milo's Unfinished Rite of Passage

Eighteen-year-old Milo dies at an amusement park after her three brothers dismiss her bone cancer as another lie. As a ghost, she watches them celebrate adopted sister Luna, erase Milo from the family, and only later discover her body, diagnosis, and tampered ride restraints. When surveillance exposes Luna paying a park worker, the brothers realize their cruelty came far too late.
