The counter-clock trilogy

What if you went back in time to stop the September 11th terrorist attacks? One man did. This is his story. Time is running out for Joshua Sinclair—he’s stuck in the year 1987—with only one mission—warn the world of the events of September 11th, 2001—the only way to prevent his father’s death at the Pentagon. But no one believes what he has to say. Even worse, a group of CIA officers are tracking his every move, trying to stop him at every possible turn. With no one in the past he can trust, Joshua must take fate into his own hands—from Chicago, Washington, and West Berlin…to the battlefields of Soviet-occupied Afghanistan.
