Burning Bright follows the Kellaway family as they leave behind tragedy in rural Dorset and come to late 18th-century London. As they move in next door to the radical painter/poet William Blake, and take up work for a near-by circus impresario, the youngest family member gets to know a girl his age. Embodying opposite characteristics – Maggie Butterfield is a dark-haired, streetwise extrovert, Jem Kellaway a quiet blond introvert – the children form a strong bond while getting to know their unusual neighbor and his wife.

Set against the backdrop of a city nervous of the revolution gone sour across the Channel in France, Burning Bright explores the states of innocence and experience just as Blake takes on similar themes in his best-known poems, Songs of Innocence and of Experience.
