An excellent twist on the living dead apocalypse theme. I read it years ago and liked it so much I recently re-read it.
From the back cover -
In Moscow, the sound of bones echo across Red Square. In America, Skeletons patrol the streets of Manhattan and blood stains the cornfields of the Midwest. While in Washington D.C.,Abraham Lincoln is heading for his third term in the White House.
The best and worst of humanity are back with a vengence, a skeletal army hell-bent on conquering the living and uniting the world under the banner of the dead. Against this global backdrop of gobal horror, a small group of refugees find themselves drawn together by a single vision and a shared fate:to determine whether the last two humans on earth will survive-or join the ranks of the newly risen.
