Penance creates an amplifier to spread Mary's hope-inspiring song across the city - but first, Mary must find her elusive voice. As danger mounts against her group, Amalia propositions an unlikely ally and sets out to expand the Orphanage's reach. Swann further entangles Augie and Mundi in his business affairs.
In the last years of Victoria's reign, London is beset by the 'Touched': people - mostly women - who suddenly manifest abnormal abilities, some charming, some very disturbing. Among them are Amalia True, a mysterious, quick-fisted widow, and Penance Adair, a brilliant young inventor. They are the champions of this new underclass, making a home for the Touched, while fighting the forces of... well, pretty much all the forces - to make room for those whom history as we know it has no place.
