In the dark days following a failed French Revolution, in the violent jungle of an alternate 1828 Paris, young cat-burglar Eponine (Nina) Thenardier goes head to head with merciless royalty, and the lords of the city's criminal underworld to save the life of her adopted sister Cosette (Ettie).

Her vow will take her from the city’s dark underbelly, through a dawning revolution, to the very heart of the glittering court of Louis XVII, where she must make an impossible choice between guild, blood, betrayal and war.
