Return Engagement — Harry Turtledove

It's 1941, and an alliance of peace holds in check the most powerful nations of the world -- but it is an uneasy peace. Japan dominates the Pacific, the Russian tsar rules Alaska, and England, under Winston Churchill, chafes for a return to its former glory.

Behind this façade of world order, America is a bomb waiting to explode. Jake Featherston, the megalomaniacal leader of the Confederate States of America, is just the man to light the fuse. Opposite him is Al Smith, a Socialist U.S. president in the Philadelphia White House. Smith is a living symbol of hope for a nation that has been through the hell of war and depression.

Featherston and his Freedom Party are determined to conquer their Northern neighbor at any cost. After crushing a Negro rebellion in his own nation, Featherston sends Confederate army planes to attack Philadelphia. In the aftermath of the CSA blitzkrieg, the war machine spins a vortex of destruction, betrayal, and fury that no one -- not even Jake Featherston himself -- can control.

THE DARKEST DAYS STILL LIE AHEAD FOR THE U.S.A., AND ACROSS THE GLOBE A NEW ERA OF WAR BEGINS.
