It is pretty unusual to see historical fiction authors giving away books on their blogs, but Susan Higginbotham is!
I've owned the book myself for a while, and have bought it with me to sunny but cold Adelaide to hopefully read while I am on holidays.
Susan's book, The Traitor's Wife focuses on the life of Eleanor le Despenser, wife of Edward II. You can read an interview with Susan at History Buff and can join in on the giveaway at Susan's blog, but you will need to hurry. There's only a couple of days of giveaways left to go!
