Tracy Kidder has made both a local impact with works such as Hometown and Among Schoolchildren, as well as a national one with Mountains Beyond Mountains. With Rough Sleepers he combines those two audiences. The non-fiction book centers around Dr. Jim O’Connell, a doctor who serves the homeless in Boston. Kidder takes readers on O’Connell’s nightly rides through the city, searching for those people who need healthcare the most. The book gives an in-depth look at homelessness both in Boston and in the American system, and balances the statistics and data with human stories of Dr. O’Connell and those he serves. Kidder’s writing style is accessible, interesting, and heartbreaking and readers who have spent time in Boston will recognize landmarks and agencies and understand them in a new way.
