Island of the Blue Dolphins is based on the true story of Juana Maria，a Nicoleno Indian left alone for 18 years on San Nicolas Island. It is a historical novel. Scott O'Dell was born in Los Angeles, at the era when exploiting the Western. Part of this book comes from his memory. When he was young, he and his friends often went to where the Indians had lived before. They played on the old canoe. So he know many things about the Indians.
This book shows a really brave girl. Her 18 years life on the island is very difficult. For me, I think this book show me some character, such as brave, unremitting, clever. It told me that we should never lose hope and we should try to find pleasure when we were in a bad situation.
