Emily Windsnap and the Crystal Caves

Emily discovers a mysterious crystal bangle that leads her, Shona, and Aaron on a quest to the Crystal Caves. They realize the crystals are tied to a conflict involving King Neptune and the Norse god Thor. To prevent a catastrophe, the friends must facilitate a diplomatic resolution between these two powerful, ego-driven rulers. SENSITIVE TOPICS: The series addresses the theme of an incarcerated parent (Emily's father in earlier books) and the complexities of mixed-heritage identity (Semi-Mer). The approach is metaphorical, using fantasy to mirror real-world feelings of not fully belonging to one group. The resolution is consistently hopeful, emphasizing family reunification and systemic change. EMOTIONAL ARC: The book begins with a sense of wonder and discovery, moves into high-stakes tension as the disaster looms, and concludes with a satisfying sense of accomplishment and communal harmony. IDEAL READER: A 10-year-old who loves mythology and is starting to realize that adults don't always have the answers. It’s perfect for the child who is the 'peacemaker' in their friend group. PARENT TRIGGER: A child might express frustration with 'bossy' adults or rules that seem unfair, mirroring Emily’s frustration with Neptune's selfishness. PARENT PREP: The book can be read cold, but knowing that Emily is 'Semi-Mer' (half-human, half-mermaid) is essential. The introduction of Thor brings in Norse mythology, which might spark questions about different pantheons. AGE EXPERIENCE: Younger readers (age 8) will focus on the magic, the swimming, and the 'cool' factor of mermaids. Older readers (age 11-12) will pick up on the political maneuvering and the critique of Neptune's ego. DIFFERENTIATOR: Unlike many mermaid stories that focus solely on romance or vanity, Kessler’s work uses the mermaid trope to explore complex diplomacy and the intersection of different mythological traditions.
