Fans of Paola Santiago and the River of Tears and Ghost Squad will root for Omega Morales as she learns to trust her newfound powers when she comes face-to-face with the Mexican legend El Cucuy.

After discovering that she has the unique ability to affect the emotions of supernatural creatures, Omega is certain she's strong enough to handle the feelings of others on Día de Muertos. But when darkness overwhelms her, it's a sign that not only is she still vulnerable but that there may be a new malicious presence in Noche Buena.
 
When a child goes missing at the cemetery, panic ensues, prompting the new sheriff to open an investigation. But then another child is taken, and another. Soon, with the help of Carlitos, Omega discovers that El Cucuy--the boogeyman--is responsible for the disappearances. And it doesn't take long for Omega to realize that, just like with La Lechuza, she might be the only one who can stop him--but at what cost?
