Jack Parker is a charming fifteen-year-old who has always skated by on his lies, especially the one about Mikey, an underprivileged (and made-up) teen who Jack 'tutors'. Mikey provides a ready-made excuse for chores, homework, tardiness, and general mayhem. It's a great plan, until one day 'Mikey' showsup for real. And then all Jack's other lies, from his super-possessive girlfriend to the roving band of alien body snatchers, start to come true as well.
