Hunt me down

Tracie is running, running from the the unknown and dangerous. She doesn't know who they are, or what they want. All she knows is there chasing her...and are willing to go to any lengths to catch her. They know all her deepest secrets, and observe her lifestyle dawn-to-dusk. They have satellites motoring her every move, cameras set up everywhere watching where she'll run to next, and even had undercover agents trying to gain her trust, acting like normal high school newbies. It all started after her ex boyfriend mysteriously disappears, leaving her with a important piece of evidence for a string of unsolved Disappearances...And if she doesn't solve this mystery just in time...she could be next.
