Chronic overachiever Prudence Daniels is always quick to cast judgment on the lazy, rude, and arrogant residents of her coastal town. Her dreams of karmic justice are fulfilled when, after a night out with her friends, she wakes up with the sudden ability to cast instant karma on those around her. Pru giddily makes use of the power, punishing everyone from public vandals to mean gossips, but there is one person on whom her powers consistently backfire: Quint Erickson, her slacker of a lab partner. Quint is annoyingly cute and impressively noble.
