Chronic overachiever Prudence Barnett 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, especially when it comes to his work with the rescue center for local sea animals.When Pru resigns herself to working at the rescue centre for extra credit, she begins to uncover truths about baby otters, environmental upheaval, and romantic crossed signals – not necessarily in that order.
