In this latest installment of entertainer George Lopez's books for children, Jorge and his chupacabra friend Carter investigate a terrifying appartition from Mexican folklore who is causing a rash of alarming disappearances . . . including Jorge's father! When a legendary monster called a chupacabra asks you for a favor, it's hard to say no! Jorge knew there were other chupacabras besides his pal Carter out there, but he'd never seen any until one named Pepe arrives pleading for their help. A mysterious weeping phantom called La Llorona, known for generations as a child-snatcher, has been haunting the area where Pepe and his family live. She's responsible for the sudden rash of missing grown-ups, including the chupacabras' trusted friend! But solving the mystery would mean secretly traveling from Jorge's grandparents' place in New Mexico to his hometown of Los Angeles, along with his loyal buddies Liza and Ernie. It's a bad idea and Jorge would get into HUGE trouble if he was discovered. But also . . . his mom is in LA and he would give anything to see her again. The young detectives embark on their riskiest adventure yet, unearthing clues that point to an elaborate scheme of vengeance. But is La Llorona real? And will her next victim be Jorge himself?
