On a rooftop in Elizabethan London two worlds collide. Shay is a messenger-girl and trainer of hawks who sees the future in the patterns of birds. Nonesuch is the dark star of the city's fabled child theatre scene, as famous as royalty yet lowly as a beggar. Together they create The Ghost Theatre: a troupe staging magical plays in London's hidden corners. As their hallucinatory performances incite rebellion among the city's outcasts, the pair's relationship sparks and burns against a backdrop of the plague and a London in flames. Their growing fame sweeps them up into the black web of the Elizabethan court, where Shay and Nonesuch discover that if they fly too high, a fall is sure to come?
