Pence, Ken. Uplift. Kindle, 2014.
I guess I blame John Scalzi’s Old Man’s War and Joe Haldeman’s Forever War for creating a genre of military space opera fantasies for geezers. First, you need a gimmick for making old guys young again. Haldeman and Scalzi use future tech resulting from near-light-speed time dilation. In Uplift, Ken Pence has his old guy get a boost from a multidimensional alien in the form of a small 11-sided polygon that essentially says, swallow me. Next thing you know, we are getting humanity ready to fight off an alien horde, literally called The Horde, that is on its way to enslave us. No surprise—Scalzi and Haldeman do it better. 3 stars.
