Ang Mga Kaibigan Ni Mama Susan by Bob Ong

A young man keeps a diary of the strange and escalating events after he is sent to live with his devout grandmother in a rural town; as he records bizarre rituals, secret gatherings, and the growing influence of his grandmother’s mysterious “friends,” he uncovers a sinister mix of folk belief and cult-like control that isolates him and leads to increasingly eerie, supernatural confrontations and a tense, ambiguous conclusion.
