Elizabeth is the newest member of the big and boisterous Sheridan family. They try to make her feel at home, but Elizabeth stays apart. She knows from previous experience in foster homes that one day she’ll be sent away.

As the story opens, all the Sheridan kids are headed to the beach for a vacation at their grandmother’s house. Elizabeth secretly looks forward to fulfilling one of her private dreams: to see the ocean. The Sheridans, on the other hand, are just too much—too prone to hugging, too loud, too enthusiastic. Only Petey, the youngest boy, is not overwhelming to be with.

Pretty soon Elizabeth has found a favorite perch overlooking the water. But her attitude threatens to ruin everyone’s vacation. It’s only a matter of time before a showdown between Elizabeth and the grandma she calls “Iron Woman” ensues. Who will win?
