This novel surprised me by being a page turner. Once I read through the first couple of chapters, I had to keep going. In Southern California the Salton Sea, once much larger and the home of a thriving resort, now has shrunk and only a few people live there. Not far away lies the Imperial Valley, one of the largest agricultural regions in the US which is close to the Mexican border. This is the setting of the story of the little town of El Valle, the surrounding areas, and the tale of two families, one rich, white landowners, the other Mexican-indigenous. Mal, one of the main characters, has always lived on El Valle, worked hard, tried to forget the disappearance of her sister, and raised two daughters alone. Another local girl goes missing, then a week later her youngest daughter also goes missing. Frantic, she searches for answers, wonders if there is a link, and keeps dreaming of the local, indigenous legend of the horse headed woman, El Siguanaba. Meanwhile readers learn about the long friendship and affair between Mal’s oldest daughter, Griselda, and the son of the valley’s largest, white landowner, Mal’s difficult, disabled mother, her father, and brother’s, one of whom is running for office after going to Stanford, and the youngest brother, Benny, who is now a detective. Not only does this work of fiction combine Latinx and indigenous cultures, it also addresses environmental collapse, family secrets, and the complex relationships between mothers and daughters.
