When an agent vanishes, leaving behind a lifetime of mystery and igniting a future of peril, a Delta Green team is pulled into a vortex of horror and deception, destiny and betrayal. From the Smoky Mountains of eastern Tennessee to the snow-covered beltway of Washington, from the depths of Fort Leavenworth prison to the sunny tropics of Puerto Rico, from the sky over China to the jungles of Cambodia, we are there, following a scarlet skein of tangled causality through time and space that threatens to ignite a war between Delta Green and its bitterest enemy. The dancers at the soul of time are calling across the gulf of infinity. Won't you join the dance?
