Beware the witch.

At the edge of postpartum psychosis, new mother Harper moves in with her own mother at their family's rural farmhouse. Soon she finds herself hunted by a threatening monster who has designs on her child.
In The Beldham, consciousness is carried by monsters and creatures — a plane of “postpartum nightmare”. The story fights on E8/E9 of the E0–E14 reality ladder, compressing motherhood, psychosis, monster, fear, family.
