Duncan is a genius straight A student, Blade is juvenile delinquent. But because of a mix up with their school records, everyone thinks each is the other one. Now, Duncan kind of likes the attention from being thought of as a real bad dude, if only the school bully would stop trying to rough him up. And Blade definitely likes being thought of as important instead of as trouble.

A few years from now, Earth will have the first contact with an alien civilisation. These aliens, known as Newcomers, slowly begin to be integrated into human society after years of quarantine.
