This book is a complete biography of Mary Todd Lincoln starting out with her grandparents which surprised me. This book is not an overview of Mary's life it is very detailed. I think it is a fair account of her life and there are some things I never would have guessed. I must admit I haven't finished the book as yet it is not one of those books you finish off in one afternoon, but I have read enough of it to know that a 4 star review is accurate.
