Berlin, September 1872. The Duncker brothers, Max and Wolfgang, own a thriving publishing business in the city. Clever, irresponsible Max is as fond of gambling and brothels as the older, wiser, Wolfgang is of making a profit. When Max's bad habits get out of hand, Wolfgang sends him to the Spa town of Homburg, to dance attendance upon a celebrity author – the enigmatic Sibyl, also known as George Eliot. As enthralling and intelligent as her books, she soon has Max bewitched.
Yet Wolfgang has an ulterior motive: for his brother to consider Sophie von Hahn, daughter of a wealthy family friend, as a potential wife. At first, Max is lured by Sophie's beauty and his affectionate memories of their shared childhood. But Sophie proves to be nothing like the vision of angelic domesticity Max was expecting. Mischievous, wilful and daring, Sophie gambles recklessly and rides horses like a man.
Both women have Max in thrall – one with her youth and passion, the other with her wisdom and fierce intelligence. Out of his depth, Max finds himself precariously balanced between Sophie and the Sibyl. What's more, Sophie worships the great novelist of questionable morals – and is determined to meet her.
A compelling Victorian novel and a playful meditation on the creation of literature, Sophie and the Sibyl balances a tale of courtship and seduction with a fascinating, lively imagining of the writer George Eliot at the end of her boldly unconventional life, and the height of her fame.
