Born on St. Patrick's Day, Charlotte planned on keeping her twenty-first birthday low key, instead of going out and getting drunk on green beer with friends. She had never been one to embrace the holiday as her birthday, much to her mother's dismay, and the last thing she expected was a cursed shapeshifting leprechaun magically popping into her bedroom in the middle of the night. Not one to feel attraction towards others, she's caught off guard when her body warms to the sexy intruder.

When Fabien gives her his curse for the day, Charlotte finds herself in an unfortunate yet suitable uniform she would have never worn, with wishes to grant, all while knowing her birthday adventures would be erased from her memory. Will she accept her fate, the holiday, and the clothes? Or will she try to defy the curse and the rules of the magical law that governs it?
