I must confess that what I loved more about the story was the glimpse I had of all these extraordinary people and how they lived. Since Theodosia goes to live in the South after her wedding there are many references to slavery and live in the plantations. Theodosia, while starting out as an engaging character ends up being too blind for too long to what her father really was - a charming scoundrel - and so set herself for much heartache.
Seton does a good job of grabbing historical figures and known facts and weaving them into fictional novels. The objects of her biographies are usually less known characters of history and that leaves her more freedom to fictionalise and romanticise their lives. Besides Theodosia there's Katherine Swynford (Katherine) and Elizabeth Fones (The Winthrop Woman). Her concern with historical accuracy and research was known but My Theodosia seems to be a highly fictional account of Theodosia's life, instead of being the final work about her it whetted my appetite for more. I was only sorry not to see more pages devoted to Theodosia's unusual education and the use she made of it. In all the references I found about her that is one of the things mentioned that set her apart from the other women of her time.
An interesting novel that should appeal to everyone interested in American history in general and Aaron Burr and his daughter in particular!
