"The Dreaming City has a million stories." The world has finally reached its final hours with Yog-Sothoth devouring time itself. John Henry Booth is not content to die and seeks out an old enemy to provide him an escape from the dying Earth. This results in him being transported to a strange monster-filled city where millions of humans live in a bizarre hodgepodge of eras. John soon finds out he's been here before, or at least some variant of him has, and he is soon founded by faces long thought dead. And what is his lost son's connection to the mysterious metropolis? The Tree of Azathoth is the third novel of the Cthulhu Armageddon series, a post-apocalypse continuation of H.P. Lovecraft's popular Cthulhu Mythos.
