Mutant science projects, a troubled werewolf, and other magic-related dangers are Jessica's new normal, but someone has started targeting the students of Coldwater High with powerful curses, and she's a suspect. A serious mistake forces her to question whether she deserves Drew and Michiru's loyalty, and with the gatekeeper's alien influence in her head, she's not even sure she can trust herself. Just as Jessica realizes she has also been hit with a lethal curse, a disastrously magical Valentine's Day leaves her cut off from friends and forces her to put her life in the hands of her worst enemy.
