The secrets of the past are blooming... and they are lethal.
Stephanie never wanted to be at the elite Academy, but the moment Principal Wills laid eyes on her antique family necklace, the rules vanished. Allowed to stay under a mask of sickening sweetness, Stephanie quickly realizes the school is hiding dark, impossible secrets. Students move like mindless puppets, and an icy wind carries a foul metallic scent that threatens to swallow the campus whole.
With the help of her reluctant friend Milo, Stephanie uncovers a classified blueprint from 1954 that reveals a massive, hidden sub-basement vault. But the mystery cuts deeper than she ever imagined. Her own family founded the school to seal away an off-world power capable of global destruction—and her heirloom necklace is the only key.
As the mysterious Vextromia orchid prepares to pulse its final, permanent wave of mind control, the principal's tragic past comes to light. With her ally frozen in fear and a mindless student body turned against her, Stephanie must find a way to destroy the radioactive garden before the vault is unlocked forever.
