Proserpina was the Grand Duchess of the city-state of Tyras. Betrayed by her brother in law, she had to flee, leaving her infant daughter behind. Shipwrecked on a deserted, unknown island, she found a ruined tower, the home of a sorceress long dead, and in company with the beast-man who became her servant, she studied, and grew powerful in the ways of magic.
After fifteen years in exile Proserpina is able to escape her prison. She comes for revenge, and finds chaos. Her enemies are at one another’s throats, her daughter has fled to escape a forced marriage, and now hides among criminals and scoundrels in the city's underworld. Seeking revenge with one hand, and redemption with the other, Proserpina must make her way through a landscape of traitors, assassins, and intrigue to forge a new destiny.
