A Very Large Expanse of Sea takes place one year after 9/11 and follows Shirin, who endures cruelty from the community around her due to her religion and the fact that she wears a hijab. She uses music as an escape, until she meets a boy who is willing to get to know her as a full person. This book expounds upon the complicated relationships we have with the people around us, and the importance of holding true to one's values, even in the face of immense prejudice.
