The Guardian's Deceit (A Vector Smith Thriller)

Vincent Smith isn't really a teacher. He also isn't "Vincent" anymore. Not in his real life. In that life he's Vector, and he carries a gun.

The rebellious 16-year-old orphan in his class has a secret, too. One she doesn't even know.

Vector Smith is a Secret Service agent. And Jess is the illegitimate daughter of the President. Someone else knows that secret, too. And now they've taken her.
