Countdown Zero

There are people in this world who live secret lives. There are people who fight the evil that lurks in the shadows so that the rest of us can live free from tyranny and fear. There are people--perhaps the person sitting across from you on the bus, or waiting tables at your favorite restaurant--who put it all on the line for us, every day, whose names we'll never know. None of these people is Carson Fender. At least, not since he was let go by the secret agency who enlisted his services to help foil a nefarious plot perpetrated by one of their former agents. Carson is back to hanging with his friends, pulling pranks, and not having to lie to everyone about how he's spending his days. And that's for the best. Isn't it? Of course, this was all before a note showed up in his school lunch, informing him that Agent Nineteen has three days left to live, and that there might still be someone inside the Agency working against them. Carson has always been able to rely on his friends--but what happens when there's no one left to trust?
