Mariko Takashi and the Case of the Gremlin Horde

Alvaro Jameson is a brand new student to the Hughes High School district. On his first day of classes, he follows a young red-headed female student with a supernatural glow that no other student seems to notice. Tracking her to a secret location, he discovers that monsters, magic and witches are real. Because he witnessed young Mariko Takashi using her powers, she loses them until he can help her prove that she can be a great supernatural detective without her magic. Can he survive his first case by helping her to find the gremlins that he inadvertently let escape, before his school is overrun?
