“It draws you in. You twist your mind into new shapes. You start to understand Caverna . . . and you fall in love with her. Imagine the most beautiful woman in the world, but with tunnels as her long, tangled, snake-like hair. Her skin is dappled in trap-lantern gold and velvety black, like a tropical frog. Her eyes are cavern lagoons, bottomless and full of hunger. When she smiles, she has diamonds and sapphires for teeth, thousands of them, needle-thin.""But that sounds like a monster!" "She is. Caverna is terrifying. This is love, not liking. You fear her, but she is all you can think about.”

“For a second, she could almost see Caverna as the Kleptomancer did, a murky, monstrous beauty, smiling her fine-fanged smile as she prepared to stretch and grow, shaking out her tunnel-tresses as they became longer and longer. Perhaps Caverna had already known that such an opportunity was open to her. Neverfell imagined her discarding the Grand Steward like a worn-out toy, and reaching for a new favourite, a man who could extend her empire and bring her new strength . . . Maxim Childersin.”

“Sometimes she felt she would like to engulf him like a trap-lantern, and never share him with anyone or anything else again, not even the light. Even his obsession with ruling Caverna pained her, as if the city were a woman, and a rival.”

“I no longer draw up maps – and maps are a Cartographer’s love letters to Caverna, his way of serving and worshipping her. She is in my thoughts all the time, but I am no longer her slave.""Then you still . . . love her?" asked Neverfell, struggling with the notion. "More than ever," her companion answered softly.”

“She’s got us, she’s got us all. Caverna. She doesn’t want to let us go. Do you know what she’s like? A huge trap-lantern with us inside her, digesting us really, really slowly, and not wanting to let any of us go. Maybe that’s the worst kind of prison – not knowing you’re in a prison. Because then you don’t fight to get out.”

“And Neverfell started to understand the beauty of flaws, those places where up and down secretly gave up their argument and shook hands, where compass points spun like a dervish and where space itself was twisted like a wrung-out flannel. These places were the dimples for Caverna’s glittering smile, her foibles, her signature. To understand them was to steal a smile, a twisted rose from her hand, a bone from between her thousand teeth.”

“I understand Neverfell, you see. For Neverfell, it is as if other people are part of her. When she believes they are in pain, it hurts her, like a wound in a pretend limb. So right now she is in pain for all the people she saw in the Undercity.”
