Excerpt:
There is so little time.

Moments ago I watched Katniss volunteer at the Reaping, and now I run as quickly as possible to the Justice Building. The events seem unbelievable. Although I always knew one of us could be drawn for the games, it never seemed realistic. Well, now it is realistic, I think harshly. All too realistic. I trip and curse under my breath. My foot throbs, and tears pool in the corners of my eyes. I start to feel sorry for myself, but I remember Katniss – wonderful Katniss who currently sits in the Justice Building waiting for the train ride to her death. I shake this thought away. Optimism, cautious optimism will rule my thoughts now. Katniss is strong and able. She can win it, I try to convince myself.

I curse again but this time my anger is directed at the swarms of people going home after the Reaping. They move like cows, slowly and without a care in the world because only a baker’s son and a girl from the Seam will die for District 12 this year. They are safe. I glance at a clock on the street. There is so little time. The Peacekeepers only keep the tributes at the Justice Building for an hour and then whisk them off to the Capitol. I break into a run. I don’t care about the people I’m shoving and stepping on. I need to get to the Justice Building before they leave.
