Looks like it could be an interesting series. Among the contributors are some of our finest historians of this period, David Blight (author of Race and Reunion), Liz Varon (author of Disunion), James McPherson, Eric Foner (The Fiery Trial) and Gary Gallagher (who has a book coming out at the end of the month or early May about the Union Army).
Hopefully, it will be available for listening by American audiences.
