The Mystery Files of Siara Marn

Siara Marn. As a kid she was always made fun of by everyone in her class. She was nerdy, and wore sweaters and big glasses. She disappeared in 8th grade. What happens when she returns years later to the same school as a senior? But this time, she's completely changed. Oh and she's a trained agent. And she's the best they have.
