Journalist and author Peter Lovenheim has lived on the same street in suburban Rochester, NY, most of his life. But it was only after a brutal murder-suicide rocked the community that he was struck by a fact of modern life in this comfortable enclave: no one knew anyone else.

Thus begins Peter’s search to meet and get to know his neighbors. An inquisitive person, he does more than just introduce himself. He asks, ever so politely, if he can sleep over.

In this smart, engaging, and deeply felt book, Lovenheim takes readers inside the homes, minds, and hearts of his neighbors and asks a thought-provoking question: do neighborhoods matter-and is something lost when we live among strangers?
