Summary of "Fallen Angels"

In my book “Fallen Angels” By Walter Dean Myers, there’s this man named Richard Perry. He is trying to hold onto his dreams in his troubled neighborhood In Harlem, New York City.  Perry couldn’t afford to go to college, and he had to go to the Army in the US to attend war in against Vietnam. His military leadership is careless and brutal.  No one in the war knows when it would end. They wonder if anyone will be able to go home, or not at all.
