Skeletons by Al Sarrantonio

In Moscow, the sound of bones echoes across Red Square. In America, skeletons patrol the streets of Manhattan and blood stains the confields 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 vengeance, a skeletal army hell-bent on conquering the living and uniting the world under the banner of the dead.

Against this bloody backdrop of global 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.

SKELETONS

Terrifying and outrageous, Skeletons is a roller coaster ride into the fibrillating heart of darkness by one of horror's scariest writers.
