After solving The Grendel Affair, the agents have another SPI File to investigate...We’re Supernatural Protection & Investigations, known as SPI. We battle the real monsters of myth and legend, but this Halloween, we’re searching for diamonds…A gala opening at the Metropolitan Museum of Art has attracted the upper crust of Manhattan—and thieves. A trio of vile harpies attacks the crowd and steals the stars of the exhibition: a colorful cluster of seven cursed diamonds known as the Dragon Eggs.In the right mage’s hands, each stone can pack a magical wallop. Together they have the power to “cure” the supernaturals of the tristate area—but for many of those vampires and werewolves, that means turning into dust.I’m Makenna Fraser, a seer for SPI. With the help of my partner, Ian, and the other agents, I have twenty-four hours to prevent total global panic, find the diamonds, and save the supernatural community. No biggie...
