Awake in the Night Land by John C. Wright

This ultimately gets Sophie expelled from the city and thrown into the freezing wilderness when she takes the blame for a theft committed by Bianca. Sophie, from Xiosphant, has both a position in an elite university and a crush on Bianca, her colleague but also a political reactionary. The plot alternates between two principal characters. On the fringe, traveling between the cities, are groups like the Citizens, who take the road as their home. Local inhabitants are mostly divided between two diametrically opposite urban locations: Xiosphant, an authoritarian city where citizens' actions are tightly controlled and any deviation is severely punished, and Argelo, a wild anarchy run by competing criminal gangs.

Humans live in the twilight zone, between the boiling heat of the sun-facing side and the frozen wasteland of the night side. The story takes place in the far future, on a tidally locked planet called 'January'. It explores themes of personal relationships, mixed with coverage of contemporary social and political issues as depicted in its alien setting. The main story focuses on two characters whose actions take them outside of the cities. It is set on a tidally locked planet, where human life, surrounded by hostile alien life, is mostly divided between two archetypically different urban sites. The City In the Middle of the Night is a 2019 climate-fiction novel by Charlie Jane Anders. Locus Award for Best Science Fiction Novel
