I'm a Sci Fi nut so I'm currently reading "Sister Time" by John Ringo.
It's part of the Aldanata series.
It's a SHTF series where the earth gets invaded by the Posleen.
Think Intelligent Centaur with an Aligator Head and a Samauri sword with a mono-molecular blade (single molecule thick, cuts through anything).
This is book 6 or 7 in the series.
So in this book Hillary DID become president and called her people to invade?
