Prison Break

A boy whose distaste levels for the town which were seemingly empty, toxic manifested itself in the color of his hair. Stereotypically, meets one of his age whose name was the color of his hair, again, translated in French that is. Oh, and did I mention the brunette or noirette is kinda creepy, a good kinda creepy though, with a fair amount of enthusiasm and passion, not enough to last his lifetime on his own. That is, until his fire was rekindled with a bang.

Both boys with hair color opposite to their energy levels meet just to have those fixed. Ha!
Also, have I mentioned that they want to be free so they decided to build flying scraps of metal, however, crappy plot twist ensues so go read it.
