His Grace of Osmonde, Being the portions of that nobleman's life omitted in the relation of his lady's story

Historical novel, set in the 17th century, for children and teens. According to Wikipedia: "Frances Hodgson Burnett, ( 1849 - 1924) was an English–American playwright and author. She is best known for her children's stories, in particular The Secret Garden, A Little Princess, and Little Lord Fauntleroy. Born Frances Eliza Hodgson in Cheetham Hill, Manchester, her father died in 1854, and the family had to endure poverty and squalor in the Victorian slums of Manchester. Following the death of her mother in 1867, an 18-year-old Frances was now the head of a family of four younger siblings. She turned to writing to support them all, with a first story published in Godey's Lady's Book in 1868. Soon after she was being published regularly in Godey's, Scribner's Monthly, Peterson's Ladies' Magazine and Harper's Bazaar. Her main writing talent was combining realistic detail of working-class life with a romantic plot. Her first novel was published in 1877; That Lass o' Lowrie's was a story of Lancashire life. After moving with her husband to Washington, D.C., Burnett wrote the novels Haworth's (1879), Louisiana (1880), A Fair Barbarian (1881), and Through One Administration (1883), as well as a play, Esmeralda (1881), written with William Gillette...Her later works include Sara Crewe (1888) - later rewritten as A Little Princess (1905); The Lady of Quality (1896) - considered one of the best of her plays; and The Secret Garden (1909), the children's novel for which she is probably best known today. The Lost Prince was published in 1915..."
