It's been 5 1/2 years since the Shift first plunged the industrialized world into darkness. Left with only a few old diesel engines and Classic Rock albums recorded on vinyl, the EMPs have forced the survivors to adapt to a world devoid of computers, bereft of a global economy and reeling without Facebook. Our favorite obsessive-compulsive Chris Jung has grown up (a little) and now leads the Vicious Rabbits Bicycle Mounted Cavalry through the necropolis of the DC Beltway region, protecting Rochelle and her allies in the Orange Pact from bandit raids. Meanwhile, Reverend Rita Luevano struggles to maintain an uneasy peace between the Unitarian majority and the Christian minority in Greater Monticello. The Orange Pact allies are threatened by foes all around. Outnumbered and outgunned, they stand against the rising tide of chaos and tyranny largely through the wily interventions of the intelligence organization known as the Swan, headed by Meredith Jung. But the darkness is closing in on this little slice of sanity in the Shenandoah Valley. Meredith knows it's only a matter of time until the Lambs of God in Lynchburg decide to attack, and when they do, there will be no stopping them. Furthermore, Meredith carries a secret so potentially devastating that it dwarves the prospect of being overrun by religious fanatics bent on their destruction. Rita is called to join Chris and his Bicycle Mounted Cavalry on a mission of utmost urgency that leads them into the heart of darkness: suburban Maryland. Along the way, they discover that nothing is as it seems. Between Meredith's secret and the revelations uncovered in Maryland, Chris, Rita and Meredith find themselves where they would really rather not be, at the center of the vortex where the entire fate of humanity hangs in the balance.
