Excellent. An interesting and well-realised world whose underlying elements are similar enough to ours that its metaphors and literalised themes - especially relating to structural oppression, power and responsibility, social change, and humanity's relationship to the natural environment - punch hard. The three female protagonists whose stories weave through before gradually and satisfyingly linking - 'Essun' (or 'you'), Damaya and Syenite - all have enough depth to convince and their stories are each equally compelling, while each contributing to layering and unfurling the Stillness's culture, history and geology (a future-world version of ours?). I liked the casual social progressiveness of parts of its society too - one character is incidentally transgender, and polyamory features without being remarkable, not to mention its general pleasing non-whiteness.
