Who is the narrator, can she or he read minds, and, more importantly, can we trust her or him?

A Long Way Gone is Ishmael Beah's memoir, so that means it's told by him and from his point of view. Since the author can't possibly know what any other characters are thinking (he's not psychic after all), we only get to focus on what's going on in Ishmael's life.
Hey, one boy soldier is enough to worry about.
