Sovay by Celia Rees (Bloomsbury, 2008)
Take a combination of Les Miserable, Robin Hood, and the pathos of Dickens and you have the format for Sovay; a French Revolutionary tale set in France and Britain. Savoy, dressed as a boy, turns highwayman to steal documents which suggest her father's wanted for seditious acts. This is a breath-taking adventure filled with patriots, soldiers and fearless citizens trying to free themselves from tyranny. Because of the length (404 pages) and the historical details of war in both countries, "Sovay" is best for older readers, 14 and above.
