London, 1858. Passionate, contradictory, and fiercely loyal to his friends, John Ruskin is an eccentric genius, famed across Britain for his writings on art and philosophy. Haunted by a scandalous past and determined never to love again, the thirty-nine-year-old Ruskin shuns polite society in favour of a quiet existence at Denmark Hill, the home he shares with his domineering parents. Reluctantly accepting a request by an Irish aristocrat to tutor her daughters in art, Ruskin becomes infatuated with his enigmatic student, Rose La Touche, an obsession with profound consequences that will change the course of his life and work. Unto This Last is a portrait of Ruskin's tormented psyche and reveals a complex and misunderstood soul, longing for a life just out of reach.
