empty nest (слэш)

Lily Potter has lived her life in relation to others: the best friend of a troubled boy, a loving wife, a dedicated mother, a grieving widow. When her son Harry leaves for university, Lily finds herself alone for the first time in decades, confronted with the unsettling task of defining herself outside of those bonds.
As the past resurfaces in the form of Severus Snape, Lily begins to wonder how things might have been different—and how they still might change—unaware that Harry is keeping a secret that will force her to confront the boundaries between love and control.
