What would happen if the Me Generation could be transported back to live among the souls of The Greatest Generation ? Nathaniel Allen and Daniel O'Shea, publicly serving as front men for a world Christian relief organization, are siphoning off food and medicine into the hands of corrupt foreign officials in exchange for blood emeralds . On a break in London, they opt for a midnight trip in a pre-WWII subway train to visit old Underground sites…but their evening jaunt turns into the ultimate tourist trap . A train wreck leaves Nate and Dan the sole survivors - and somehow transported back to 1940 London at the dawn of the Nazi Blitz. That is where their perilous adventure in time begins as their search for a way home leads them to love they dare not return, into a plot to drive England into financial ruin and, perhaps, to a chance to redeem themselves in the past for their future. Or is it their present? The action and intrigue do not stop until they - and you - learn the answer in Time Step .
