Several decades after human astronaut Leo Davidson's adventure on the ape world, ape society has been torn apart from within by a horrible civil war that's erupted between ape rebels advocating human integration and the fearful but powerful ape regime. Is the ape Seneca and his scattered but loyal followers of humans and apes enough to defeat the charismatic Shiva and her imposing ape army? The conflict has reached a bloody stalemate. But Shiva has a deadly secret that will end the war...and wipe out mankind! After all, the only good human is a dead human!
