The Rebel Within, by Lance Erlick Book Review

This is a dystopian near-future novel and the start of a series with at least one sequel.  It's told in present tense, which isn't my favorite.

Sometime in the early 21st century, either right-wingers tried to turn back the clock, or hard-core feminists staged a coup. Either way, the Second American Civil War resulted and was won by the hard-core with the help of mech warriors. These are like Heinlein's Starship Troopers, but all women. Space and the rest of Earth seem not to exist. 

Seventeen years later, men and boys have been forced from power, and from most areas by zoning commissions. They aren't wanted, but are hunted down and killed or imprisoned if they try to escape. Most of the United States is the Federal Union, though traditional society, more or less, holds out in the Outlands (Appalachia, the southwest border, possibly elsewhere).
