A wildly original blend of social horror and razor sharp satire, The Anthill is a searing exploration of privilege, racism, and redemption in the Instagram age. Lina has come home to the country of her childhood. Sent away from Colombia to England after her mother's death twenty years before, she's searching for the one person who can tell her about their shared past. She's never forgotten Matty--her childhood friend and protector who now runs The Anthill, a day care refuge for the street kids of Medellín. Lina begins volunteering there, but her reunion with Matty is not what she hoped for. She no longer recognizes Medellin, now rebranded as a tourist destination, nor the person Matty has become: a guarded man uninterested in reliving the past she thought they both cherished.
As Lina begins to confront her memories and the country's traumatic history, strange happenings start taking place at The Anthill: something is violently scratching at the inside of the closet door, the kids are drawing unsettling pictures, and there are mysterious sightings of a small, dirty boy with pointy teeth. Is this a vision of the boy Lina once knew, or something more sinister? Did she bring these disturbances with her? And what will her search for atonement cost Matty?
