Ideas equal Energy (I = E). That’s the tech magic discovered at the Tower of Babel after the flood of Noah; then that tech blew up and the world became like something out of a Mad Max film. Now dimension traveling cats bridge the past to modernity, and a man from the time of Babel crosses millennia to New Jerusalem at the end of all things. On the way there’s a smattering of romance, we see what church is like in North Korea, and a dad reconciles with his autistic Japanese daughter. Oh, there are also aliens, Yakuza, Russian mobsters, North Korean intelligence agents, AI, quantum AI, floating islands, and dragons.
