Clove, Cato, Katniss and Peeta were all victors. I think District 2's mentors were Brutus and Enobaria. Cato and Clove didn't know each other until the reaping. They start a relationship during the few days before the games.

I think there were 3 chapters with smut (last night before the games, during the games when they had to get firewood, and after the games).

Cato was the playboy type. He 'did it' with almost every girl in his district (I think?). Clove played hard-to-get, not easily succumbing to Cato's womanizing ways. I think there was a chapter where they danced and Cato told her to admit her true feelings, making Clove leave him in anger.

This is all I can remember. I'm not even sure if they are all connected in one story. It is one of my favorite Clato stories and I really want to read it again.

PM me if you know the title/author or if you have a copy.
