A Probationary Professor is looking for assistants on a perilous venture. Her doctorate covers the ritual practices of the Starved Men, and she has a theory — described by her colleagues as brazen — about a missing heretical sect within their order. To prove it, she needs to reach the cavern roof. That means a palaeontology dig unlike any other: not down, but upwards. The Starved Men are aware of the expedition and not pleased about it. Certain sacrifices may be necessary if you want to return from the roof in the same number of pieces you went up with. A Fallen London story about what lives above the city.
