Dualed by Elsie Chapman

You're a twin. You must prove your worthiness to use up some of the communities' valuable resources by murdering your twin if you want to live to be an adult. And there's a time limit. And you can't just nuke everyone, but a few deaths on the side aren't a big deal. And rich kids hire assasins to do their dirty work for them. Alright, take the love story drama between Katniss and Peeta and shove it into this world and BAM! you've got Dualed.  It's fun to read, but the last quarter felt too much like Hunger Games to me.
