Query: Great Book!

By Olivia CassadyThis book is about a man who is a diver and how he helps a baby dolphin. One day he was diving when he saw three dolphins swimming toward him. He didn't know what they wanted at first, but a couple minutes after, he realized that they wanted help. He knew that he was short of supplies, but he did what he could do to help them. There was a fishhook in the baby's tail so the diver got out a knife and tried to cut the string. Then, the next thing he did was to get the fishhook out of the baby's tail. The baby was saved, but then three ugly sharks came swimming toward them! The father shark tried to avoid them while the others swam up to the surface for safety. They escaped the sharks and said goodbye to the man. So, from that moment on the man believed that he would see them again. This is a great book about man and dolphin. I recommend that you read it!
