Kevin Anderson is moving along through his life, finishing up college, and getting ready to leave New York for an internship rebuilding San Francisco after an immense earthquake.

Then the Visitors arrive; a race of human-like aliens touch down in several cities around the globe, including SF, and nothing will ever be the same. When Kevin's company is given a contract to build a facility for the Visitors, he forms a friendship with 'Bel, one of their number. But is 'Bel so alien after all?

They seem so human, albeit much larger, but they possess some odd characteristics and seem to be hiding something. What secrets do they carry, and where, exactly, are they from? Before Kevin can get to the bottom of his questions, political disasters and miscommunications occur, and the Visitors are expelled. 'Bel and his emissaries are very clear that certain actions on the part of the U.S. will have grave consequences upon his people and their world, but no one listens except Kevin, who has fallen in love with 'Bel.

Now the young man is on a mission to unravel the Visitors' secrets in order to prevent the death and destruction of Visitors and millions of Americans.
