R. F. Kuang's Katabasis is a descent — literally and metaphorically — into the underworld of grief, memory, and the price of knowledge. Following the massive success of Babel and Yellowface, Kuang delivers a haunting narrative that blends classical mythology with speculative fiction. The title itself refers to the ancient Greek concept of a journey to the underworld, and Kuang uses this framework to explore what it means to confront the dead, the past, and the parts of ourselves we've buried. The prose is razor-sharp, the world-building is layered with academic rigor, and the emotional core is devastating. This is Kuang at her most ambitious and personal.
