Call It Courage

I really enjoyed the book, Call It Courage by Armstrong Sperry. I liked the beginning of the book because when the auther said that there was a boy who was afraid of the sea, it made me wonder, "why is the boy afraid of the sea?" and made me read on. But, the ending was confusing because it said that Mafatu was exhausted and fell to the ground and I'm not sure if he died or not. I liked how the auther explained descriptively about the strong waves and wind that killed Mafatu's mother. I think that Mafatu's father should have supported his son instead of being disappointed at his cowardness. But at the end, Mafatu could prove to his father that he was a very courageous boy.
