The language doesn't involve complicated words. However, Tommy goes off flirting three or four times and is attracted to a naked lady painting. I'm a fan of adventure stories such as this one which involve some skirmishes. There are no particularly violent scenes, but there is one where a guy gets shot by a speargun and bled, attracting sharks. This book also educates kids about some history about missing treasure. The book teaches about how teamwork and perseverance are important to a team. The Kidds are great role models since they work together. Overall, this book is really nice and exciting.
