A Mermaid in Middle Grade Book 4

Book four of A.M. Luzzader's mermaid series raises the stakes considerably: Brynn strikes a reckless deal with a sea witch to protect her place on the dance squad, and the consequences spiral into an environmental crisis and a hunt for ancient scrolls. What makes it work is that the moral arc is clear and honest — Brynn's shortcut causes real damage, and she has to own that. Environmental themes about ocean pollution feel natural rather than preachy. Short chapters keep the pace moving for newer middle-grade readers. The main caveat is that jumping in at book four without reading the earlier installments will leave readers missing context, and formal critical coverage is thin outside enthusiastic reader testimonials. Families seeking clean, consequence-aware fantasy fiction will find this a solid pick.
