This is the kind of middle-grade novel that wins awards for good reason—it's beautifully written, emotionally intelligent, and treats kids as capable of handling big, hard feelings. The jellyfish science is genuinely interesting and woven seamlessly into Suzy's journey through grief.

That said, this isn't a beach read. It's heavy. A child dies, and the entire book is about processing that loss. Some kids will find it cathartic and profound; others might find it too sad or slow. The fact that Suzy stops speaking adds to the contemplative, internal quality that won't work for every reader.

The stealing subplot is handled thoughtfully—Suzy knows it's wrong, feels guilty, and faces consequences—but it's worth discussing with your kid. Overall, this is an excellent choice for thoughtful, curious middle schoolers who are ready for literature that doesn't shy away from life's hardest questions.
