Samantha Power, a professor at Harvard, met Sergio Vieira de Mello when she was a journalist in Bosnia in 1994. Although he charmed her as he did everyone else, she has written a balanced biography of the flawed but dedicated and likable man. While Power impressed the critics with her research, she failed to convince all of them of her arguments. Several reviewers also noted that Power’s writing, laden with detail and subtle layering, doesn’t rise to the level of her Pulitzer Prizeâ€"winning A Problem from Hell: America and the Age of Genocide (2002) until the very end, when she recounts Vieira de Mello’s last moments. As much a critique of the United Nations and its policies as the story of a man battling injustice, Chasing the Flame, despite being cited as a somewhat slow read, is a significant contribution to our understanding of global affairs and the future of peacekeeping.
