“Vincent Ventura, monster fighter extraordinaire, can’t believe the house at 666 Duende Street has attracted yet another creepy creature! In fact, this time there are several unusual beings, including two boys who disappear and reappear-are they ghosts?!? And the lady in white with fiery glowing eyes who calls out for them? Is she … La Llorona?!? And who is the other young woman? The next day at school, Vincent and his cousins Bobby and Michelle meet a new substitute teacher, Ms. Malin Che, who just moved into the haunted house. What is her connection to La Llorona and the unusual children? At least this time, the kids have new friends to help solve the mystery: Sayer, who they helped in a previous battle with trolls, or duendes, and Zulema, a witch owl who was the target of evil witches. As the relationship between Vincent and Zulema evolves, becoming more complex and exciting, so too does the current case! Two new beings turn up: a hideous figure dressed as a Mexican cowboy whose face is devoid of flesh and a second spooky woman! Ms. Che, a Latin American folklore expert, tells them about el Charro Negro and the weeping women collectively called Cihuateteos. This bilingual book for intermediate readers, the fourth installment in Garza’s Monster Fighter Mystery series, follows the nail-biting battle for the souls of two boys! Will Vincent and his friends be able to save them from the monsters’ clutches?!
