In the hidden underworld of magical London, orphaned children survive in overcrowded wards and the streets, where safety is traded for alliances and names are treated as dangerous liabilities. Among them, a girl who no longer remembers who she once was becomes part of a small network of street kids led by two older boys, Bats and Crow, who act as her closest thing to family. When a missing pureblood child is unexpectedly seen alive years later, she is no longer a lost heiress—but a street survivor shaped by theft, loyalty, and survival.
