Ryan David Jahn's novel, Good Neighbors, does a very good job in bringing to life the social pyschological phenomenon known as the bystander effect, also known as the Genovese effect. This phenomenon refers to cases where individuals, such as in the Kitty Genovese murder case in 1964, do not offer any means of help in an emergency situation to the victim when other people are present. The probability of help has in the past been thought to be inversely related to the number of bystanders; in other words, the greater the number of bystanders, the less likely it is that any one of them will help. The mere presence of other bystanders greatly decreases intervention. This happens because as the number of bystanders increases, any given bystander is less likely to notice the incident, less likely to interpret the incident as a problem, and less likely to assume responsibility for taking action.
In Jahn's Good Neighbors, a young woman, Katrina Marino, is returning home from her shift at a local bar when she is brutally attacked in her Queens apartment complex. Good Neighbors is the story of the woman's last night -- and of the bystanders who kept to themselves. Jahn does a credible job in creating a series of interlocking vignettes playing out the personal dramas involving several residents in Kat's apartment complex, resulting in their ignoring her screams for help during the two hours following her brutal attack. Good Neighbors' sense of suspense and urban menace brings to mind Hitchcock's Rear Window, as well as the movie Crash. On this dimension I would give the book a 4-star rating.
However, in terms of Jahn's ability to create fully developed characters and sub-plots, I would give the book a 3-star rating. For me, the characters seemed a bit too stereotypical, and the personal drama vignettes involving the neighbors, while interesting, seemed to lack sufficient depth to care about their lives. Perhaps, this is a result of Jahn's trying to pack too much into a book of only 280 pages.
Despite these criticisms, Good Neighbors is a pretty good book from an author with a lot of potential.
