She and her friends try to secure a hangout spot in an unused building, but they uncover a heinous plot to turn the academy into a haven for the undead! Later, a splash of mandrake sap imbues Mary with a constant mesmerizing charm that captivates anyone who sees her. It sounds swell—except it means being stalked by swarms of drooling fans! Also, one of the slime research society's experiments gets loose, growing so enormous as to threaten the safety of the school itself! Can Mary cleanse the unused building of its undying spooky spirits, herself of the mandrake's unrelenting aroma, and the campus of its unceasing ooze growth without drawing too much attention? Or will the legend of the White Princess prove as immortal as the forces throwing wrenches in her plans?
