driver sees nothing and speeds away. Maisie and her
grandfather take the dolphin to their hospital. The person
who hit the dolphin asks Maisie’s father if he would like
to sell their home and the hospital. He wants to build a
big hotel on the land which upsets Maisie. When Ben, the
dolphin, gets better she feels she is losing her home and
