I'm Different

The 3rd Volume in this series, I Know Who I Am is about Gerald who wonders why his friend Jason behaves differently from everybody else even though they share many things in common, such as living in the same neighbourhood, going to the same school, are in the same class, and enjoy the same kind of games and activities.
What Gerald notices about Jason fascinates him so much that one day he makes up his mind to speak to Jason about it. Jason opens up to him and what Gerald hears leads him to make the greatest decision that changes his life forever.
