West Side Story

Author: Irving Shulman (novelization)
Reviewer's Age: 12

Based on the Bard's play, "Romeo and Juliet". The Jets and the Sharks are two gangs in a gang-war thing with each other. Maria, sister of the gang leader dude, falls in love with Tony, the other gang leader's best friend, which obviously causes some problems among the gang people and stuff. So if you've read Romeo and Juliet, you basically know what to expect since, well, West Side Story was based on it.
