For all the talk of the Civil War's pitting brother against brother, no single book has told fully the story of one family ravaged by that conflict. And no family better illustrates the personal toll the war took than Lincoln’s own. Mary Todd Lincoln was one of fourteen siblings who were split between the Confederacy and the Union.

With brio and rigor, Berry fills a gap in Civil War history, showing how the war changed one family and how that family changed the course of the war. As they debate each other about the issues of the day and comfort each other in the wake of shared tragedy, the Todds become a singular microcosm and metaphor for the country as a whole.
