Seventeen-year-old Milde is from the Outskirts, a place beyond the mountains where the dirt is corpse-rich, where mothers and daughters, banished from society, make their living – without rights, access to care, or legal status. But Milde refuses to accept the order of things and, together with some friends, she revolts against the government's injustice. Arrested, imprisoned, and tortured, Milde is eventually presented with a final choice: to be executed publicly or, as part of an experiment, to be launched into space, into a black hole called the Mass. She chooses the Mass, opting to face its fathomless depth and loneliness rather than hurt the morale of her weary allies back home. Collapsing and expanding myth and reality, Event Horizon is an exquisite existential novel, dark as deep space, woven with reflections on oppression, solidarity, trauma and loss.
