Oxford, 1862. Mary Prickett takes up her post as governess to the daughters of the Dean of Christ Church, but there is a problem: Mary does not like children, especially the precocious Alice Liddell. When Mary meets Charles Dodgson, the mathematics tutor, she is flattered by his attentions. But Mary is determined to become Mr Dodgson's muse - and will turn all the lives around her topsy-turvy in pursuit of her obsession.
