The anomaly called the Breach is the government's most carefully guarded secret.

As the U.S. President addresses the nation fromthe Oval Office, a missile screams toward the White House. In a lightning flash, the Chief Executive is dead, his mansion in ruins, and two cryptic words are the only clue to the assassins' motives: "See Scalar."

Now Travis Chase of the covert agency Tangent--caretakers of the Breach and all its grim wonders--along with partner and lover Paige Campbell and technology expert Bethany Stewart, have only twenty-four hours to unearth a decades-old mystery once spoken of in terrified whispers by the long since silenced. But their breakneck race cross-country--and back through time and malleable memory--is calling the total destructive might of a shadow government down upon them. For Travis Chase has a dark destiny he cannot be allowed to fulfill . . .
