Given the set-up, most readers can probably predict where this book is headed. That's okay. A standard plot gives MacPhail room to include a lot of silly details that will appeal to the average kid's sense of humor. There is some gross humor but nothing over the top. It's also worth noting that the strongest, bravest, most valuable members of the crew are female. It's nice to see female characters who are bold and aggressive and ultimately positive.

Great way to reach historical content. Enjoyed the book and looking forward to more. Simple story with content.
