This story is about a boy named Billy. He gets bullied by a boy named James and his gang (they joined in fear of getting bullied). He swims nearly every single day. One day a new boy came and stopped the bullying for a few days. Soon after, they became friends. A few days after on one swimming trip. A talking mackerel said Kezdodik.

The next day Billy came to Patrick’s house. He told Patrick about the fish and then felt stupid so he ran out of the house. The next day at school he tried to stay away from Patrick but Patrick caught up to him. He told Billy that believed him and Billy was very relieved. He told Billy that the fish was talking Hungarian. When Billy asked where did the fish learn Hungarian, he said that fish travel. He also said that it was a code and that the other piece of the code is Kesz.
So the next day he went swimming again and the fish came, he said the code and they swam. Billy didn’t need to go up for air since if he touched the fish he got the power to breathe underwater. Billy had lots of fun every time he visited the fish but one day they wanted Billy to stay with them and tried to drown Patrick as he couldn’t swim. Patrick got out alive.
I loved the book and recommend it.
