The Bone Season, the first in Samantha Shannon's intoxicating urban-fantasy series set in 2059 in Scion (a dystopian version of England), ended with young Paige Mahoney escaping from a penal colony in the secret city of Oxford. Her Rephaim masters — immortals who feed upon the auras and blood of human clairvoyants like her — were in hot pursuit.
The Mime Order opens with Paige on a train back to the Scion citadel of London, wounded and bleeding after leading her uprising.
