I was mesmerized by this book, and dreaded having to stop when it ended. The author manages to convey an intimate, detailed, and presumably accurate account of life in an Indian slum--a life filled with unimaginable filth, poverty, and danger. She (Katherine Boo) wrote this nonfiction book as if it were fiction--the book opens with a description of a crisis in one young boy's life, then traces the roots of the crisis and expands to its eventual resolution. By the end, the reader has not only gotten to know many of the inhabitants of the slum quite well, but also cares deeply about what happens to them. This gripping account is all the more amazing because it is true--the author goes into great detail about how she determined the facts that went into her account, and the hours of interviewing and corroboration she required before including details into her work.
