Sure. 'The Pilgrim's Progress' is a well - known devotee fiction story. It follows the journey of a man named Christian as he travels towards the Celestial City, showing his great devotion to his faith. 'Jane Eyre' is also a good example. Jane is deeply devoted to her principles and her love for Mr. Rochester, despite all the difficulties they face. There is also 'Les Misérables' where Jean Valjean shows devotion to a new life and to helping others.
There are many. 'A Tale of Two Cities' has characters like Sydney Carton who shows ultimate devotion in the end. He sacrifices himself for the woman he loves. 'Wuthering Heights' shows Heathcliff's intense and somewhat twisted devotion to Catherine. Also, 'Moby - Dick' can be considered in a way, as Captain Ahab is extremely devoted to his quest of hunting the white whale, though his devotion is a bit of an obsession.
