I was so confused by this book. I agree with a fellow reviewer- it was written for a young early reader (1-3 grades) audience but has some more mature content. There’s alcohol, detailed fight scenes, peril, guns, violence, poaching, and animal abuse. My sensitive 4th grader struggled with this book. Another thing… is this even a true story? If it is, the content doesn’t seem as big of an issue to me. True stories are not always super clean content wise. But I never found anything indicating that this was based on a true story. The first book, Dolphin Adventure, does say on the cover that it’s a true story. My daughter loved that book which is why we sought this one out. She could hardly finish it and likely won’t read the last book in the series. As it is, I would probably not recommend this book for early readers due to the content. Definitely not for sensitive or new readers.
