A Child Remembered

Libby’s Brief Life
Tender memory
Megan remembers Libby as small, quiet, and good. Even while describing an unplanned pregnancy and an unprepared home, she speaks of the baby with affection.
A lasting attachment
The child’s death becomes a defining loss rather than a closed chapter. Megan’s guilt and longing remain present in her adult life, though she rarely shares them.
A Grave Kept Secret

Stones by the Track
A hidden resting place
Megan and Mac bury Libby near their isolated home and mark the grave with stones. The burial preserves the child’s location while concealing her existence from the outside world.
Separation from the past
Mac disappears, leaving Megan alone with the memory. The physical grave remains, but the silence around it prevents mourning from becoming shared or acknowledged.

Megan tells Kamal how Libby died and how they buried her. Naming her daughter makes a private memory briefly shareable.
