Sparrow tells the story of Jacob, son of no one, last survivor of an abandoned British Roman town. Raised in a brothel on the Spanish coast in the waning years of the Roman Empire, a boy of no known origin creates his own identity. He is Sparrow, who sings without reason and can fly from trouble. His world is a kitchen, the herb-scented garden, then the loud and dangerous tavern, and finally the mysterious upstairs where the 'wolves' - prostitutes of every ethnic background from the far reaches of the empire - do their mysterious business. When not being told stories by his beloved 'mother' Euterpe, he runs errands for her lover the cook, while trying to avoid the blows of their brutal overseer or the machinations of the chief wolf, Melpomene. A hard fate awaits Sparrow, one that involves suffering, murder, mayhem, and the scattering of the little community that has been his whole world.
