I'm looking for the title of a book I read two years ago. It was an autobiography of a family that immigrated to America from either Somalia or Kenya and it's in the perspective of one of the kids in the family. He talks about how his family struggles and what not. I remember in the book his brother got a job and gave money to a homeless guy regularly. The main character also grows up to go to some prestigious school and later becomes a public speaker. Also I believe the title had the word "angel" or "wing" in it. That's all I can remember, anyone know the name of this book?
