A Long Way Gone Ch. 21

I felt like this last chapter didn't really complete the book. I want to know more about what happened to Ishmael Beah afterwards. But considering the name of the book, A Long Way Gone: Memoirs Of A Boy Soldier, I guess it really was the end of his soldier life. I personally thought that this was an extraordinary book. But I'm really interested in knowing what happens next. I guess I'll just have to find out when Ishmael Beah speaks at Butler. 

I was really sad that Ishmael's Uncle died, because I really liked his personality. He was always trying to make sure that Ishmael felt comfortable in his surroundings. I think it was really good that Ishmael was able to leave for America when he did. Even though he was separated from his family again, I thought it was the right choice for him to make. He wouldn't have to worry about being involved in the war anymore. And he would be able to start his life over, with real possibilities for himself. 

I was a little confused about the metaphor of the monkey. I didn't really understand what he meant. Maybe someone could fill me in. Please.
