Ravenstone (Book 1, The Ravenstone Chronicles)
Born into a privileged life in London, all that is required of Georgiana Wyndham is to live a life of virtue and obedience. She fails at both. Crippled by her father's severe beating, she remains strong and refuses to allow him to crush her indomitable will. When her father threatens those she loves, Georgiana knows that only way to stop him is with a knife through his heart.
