Marx is one of the main characters in the YA fiction I'm writing. He is partnered up with the VP character, Suavez.
Suavez and Marx are two high school freshmen who have very different backgrounds: Suavez is a Mexican/American charmer, and Marx is a self-absorbed emo kid. The two have been best friends for years, brought together for the passion for movies, TV, and games. Marx even has his own version of Gaming.
Nothing can come between them. Or at least nothing did, until, as part of a Game, they started investigating the missing puzzle piece behind a tragic school shooting that took place 2 years earlier. Suddenly the Game becomes life or death.
This isn't my query pitch. Just a start. Consider it practice.
