What Turtledove book should I get?

[FEMA Camp Administrator]

Right now I'm at the library and got only twenty minutes. There are a couple here including:
- the 2nd war between the USA and CSA
-What if Chamberlain stood up to Hitler
-the one with Woodrow Wilson as President of the CSA while TR heads the US
-THe one with assistant secretary of defense FDR andn a Dewey/Truman ticket (I think it's here)
-The one with that one dude who's name I can't remember as President of the CSA under the Freedom Party
-the one that has Coolidge and Smith as candidates for the Presidency.

Hopefully some of you can help me out here.

I ended up with "The Great War: American Front". No, I have not read Guns of the South, but I have a little bit of familiarity with the series. I chose this book out of the selection due to how awesome I thought it'd be having Woodrow Wilson as CSA President facing the USA's Teddy Roosevelt.
