Would you take a job that could change the world? It's what you have prepared your life for, but the gorgeous Argentine diva that would be your boss wants you killed, or so she says. Whether you take the job or not, you are sworn to secrecy. Like a switch delivering power to a light bulb, clarity of intentions is hard to hide once the electricity arrives. Or does the light just create shadows of what is really happening? In Argentina, Cambalache means junk shop or bazaar. Why would someone name one of the greatest inventions since fire or the wheel after a rummage sale? Travel to the end of the world, or is it the beginning of the world, to one of the most enigmatic countries on the globe to find out. Leaders of nations, former and future rulers, states, and secrets collide as a dangerous tango spirals out of control.
