Sailing The Pacific

Hi bloggers so today i will be telling you a book called Sailing The Pacific By Maria Samuel. So today i will be telling you a summary about this book. Before i tell you about the summary i will be asking some questions.
1.what does A.D and B.C mean in the book?

2.would you read this book?

3.who would you recommend the book to? why?

now I will be telling you the summary what I learned in the book.
I learned back in the day that when they sailed they used the clouds,birds,stars and sea movement. 

I will recommend it to schools so they could learn about voyagers and sailing. 

Thank you for reading and hope you answer my question and read the book.
