El valle de los caballos (Valley of the Horses)

Many readers praise the book's initial focus on its protagonist, Ayla, as she navigates the challenges of prehistoric survival alone. Her ingenuity, resourcefulness, and independence are highlighted as compelling, with many enjoying her development of essential skills and her unique relationships with animal companions. The author's meticulous research into the Ice Age, encompassing anthropology, archaeology, and the natural world, is frequently commended for creating a vivid and immersive setting. This detailed world-building and the exploration of ancient environments offer a fascinating backdrop, drawing readers into a plausible depiction of early human history.

However, a significant number of reviews express disappointment, noting a sharp decline in quality compared to the first book in the series. A prevalent criticism centers on a dramatic shift in genre, with the narrative evolving into what many describe as an overly explicit and repetitive romance, overshadowing the survival themes. The introduction of a new male character, Jondalar, is frequently cited as a major detractor; many readers found him idealized, uninteresting, and that his presence diverted the story's focus away from Ayla. Critics also point to a perceived lack of plot progression, repetitive descriptive passages, and certain implausible elements, such as the protagonist's rapid acquisition of new skills or language, which some felt strained credibility and bogged down the pacing.

Overall, the book elicits a deeply divided response among readers. While some found it an engaging continuation of the series, particularly the early sections detailing Ayla's self-reliance and the rich historical backdrop, many were ultimately deterred by the shift towards a romance-heavy plot and the perceived flaws in character development and pacing. This book would likely appeal to readers who appreciate extensive historical detail and themes of survival, and who are either tolerant of, or specifically seeking, explicit romantic narratives within a prehistoric setting. Fans of the first book might find the initial chapters satisfying but should be prepared for a substantial change in narrative emphasis as the story progresses.
