Serena Davidson leads two lives. At school, she's a morbidly obese, stupid, nerdy, bitchy, slutty, and a teacher's pet. But at home she's the scrawny vegetarian pushover. What would possess someone to wear a fat suit every day? And what happens when someone finds out?

Antonio Martinez has a hard time fitting in. For one, he wasn't born in the USA and as a result, has a funny accent the kids at school made fun of. New money was looked down on in his private school, and so the former top of the class had it out for him for stealing her spot. Antonio didn't think things could get any worse until his mother asked the son of her long-term boyfriend to keep an eye on him and his siblings - in other words, become their permanent babysitter. And that was how Antonio's social life was completely ruined.
