First published 2024
Percy Jackson faces his senior year with an unusual problem. He needs three recommendation letters from Greek gods to enter New Rome University. After earning one by recovering Ganymede's chalice, he accepts a second chance from Hecate. The goddess of magic wants Percy to watch her pets during Halloween week while she travels. The job seems simple enough until he meets her animals: Hecuba the mastiff and Gale the polecat, both as temperamental as they are magical. Percy brings Annabeth and Grover to help manage Hecate's sprawling mansion. The goddess warns them against touching anything in her home. While Percy and Annabeth attend school, Grover discovers a strawberry potion in the laboratory. One sip transforms him into a giant, frenzied goat who tears through the house before collapsing. During the chaos, both pets escape into the world. Now Percy and his friends must track down two dangerous magical animals and repair the mansion before Hecate returns on Saturday. Their college dreams hang in the balance as they race against time.
