Oxford, 1862: As Mary Prickett takes up her post as governess to the daughters of the dean of Christ Church, she is thrust into a strange new world. Mary is desperate for change, but there is a problem: Mary does not like children, especially the precocious Alice Liddell. When Mary meets Charles Dodgson, the Christ Church mathematics tutor, she is flattered by his attentions, and Mary begins to believe that she could be more than just a dowdy governess.
One sunny day Mr Dodgson tells the story of Alice's Adventures in Wonderland. But Mary is determined to become Mr Dodgson's muse - and will turn all the lives around her topsy-turvey in pursuit of her obsession.
