Summary from Goodreads:
Sixteen-year-old alien Val Stone was born for one mission-kill teenage Randolf "Rolf" Cartier before he fulfills the prophecy, becomes the future American president, and murderers thousands of her kind.
Val is ready to sacrifice herself for the good of the prophecy. She's learned every detail of Rolf's life. She knows when he wakes, each step he takes throughout his day, and the exact time when he falls asleep. She's prepared to strike.
But what she doesn't know is that Rolf's been watching her, too. Waiting for her. Ready to overpower her and save himself. Only when the day arrives, doubt overcomes purpose, and suddenly they discover the prophecy was all a hoax.
Now they're running against the clock, desperate to reveal who created the fake prophecy before the human killing spree becomes the complete wipeout of the human race.
