Brotherless night by V., Ganeshananthan,

Sixteen-year-old Sashi wants to become a doctor. But over the next decade, as a vicious civil war subsumes Sri Lanka, her dream takes her on a different path as she watches those around her, including her four beloved brothers and their best friend, get swept up in violent political ideologies and their consequences. She must ask herself: is it possible for anyone to move through life without doing harm?
