In this alternate ending of the Clato fanfiction "Needing the Impossible", Cato and Clove make it to the end of the Hunger Games and come out the victors. I could give you a lame synopsis, but I'd rather you just read it for yourself and tell me what you think :)

Clove and Cato both won the 74th annual Hunger Games, despite the Treaty of the Treason only allowing one victor. As a result, both of them have fame, fortune, and not a care in the world for the rest of their lives. What more could either of them ask for? Unbeknownst to them, tension is rising in Panem as a whole, but District 2 seems to forget about the fact that 75 is a multiple of 25...until the clock strikes 13 and time runs out for everyone else. ...and Clove and Cato find themselves at the center of the vortex of chaos with their sense of direction and their sanity on the line. Can they overcome their differences and hold their heads high during the Victory Tour? Or did they bite off more than they could chew during the 74th annual Hunger Games?

She's fought against her family's poverty and has to keep fighting to keep what she has. He comes from a wealthy family and can have anything he wants with a simple request. But both have become prideful. Cato and Clove both believe they are self-sufficiant, cold people. So when arrogant meets arrogant, and they're forced to cooperate if they ever hope to enter the Games, can they keep from killing each other long enough to start working together? Or are they both destined to lose everything they've fought for so far?
