This is a good book for kids interested in sharks and conservation. Leiren-Young covers cool shark facts from around the world (including new discoveries as recent as 2021), challenges sharks face, and various shark activists and the work they do to protect sharks. While the facts are there, there's a stronger emphasis on the challenges sharks face (which can get sad, though Leiren-Young balances it well), activism (particularly around the Sharkwater films), and humanizing sharks. 

The end of the book has a list of actions to empower everyday readers to support sharks, but it’s very brief and isn’t given the same attention as sections on global activism (both adult and youth activism), though I don't think this was intentional. While the activism portions will be inspiring and cool for young readers, parents should be prepared to have a bigger conversation with their kids about the concrete and everyday ways they can help sharks without becoming world-famous child activists. If they want to go big, that's amazing and I'm so glad Leiren-Young shows that it's possible, but I wish there was equal emphasis on how noteworthy it is for kids to be everyday heroes too.
