What type of tone did the book end with?

I think that Beah has greater insight into war and Africa. He comes to the sad realization that ideas of violence in Sierra Leon have not changed that much since he was a child. Beah again points out the effects of war on the children, this time in observing his younger cousins: “Children played guessing games, telling each other whether the gun fired was an AK-47, a G3, an RPG, or a machine gun” (p. 205). Childhood games have transformed into a competition to name the weapon of choice; innocence has once again been lost to violence.
