Words from me:
i'll make a review about this later on...

Summary: (Spoiler) click here for the link.
Fifteen year old Vicky Austin is spending the summer on Seven Bay Island with her family to visit her maternal grandfather who is dying of Leukemia. At the beginning of the story, Vicky is seen standing at a funeral for Commander Rodney, a family friend. Nearby stands the commander's wife, and his two oldest sons, Leo and Jacky who own a launch boat business. It is at the funeral that Vicky first meets Adam Eddington, an intern at the Island's research base and a friend of Vicky's brother, John. When Vicky and her family return home she sees Zachary Gray, an old friend whom her family does not particularly like. It was Zachary who had indirectly caused Commander Rodney's death; the commander had gotten a heart attack while saving Zachary from a suicide attempt. The news of this sets Vicky on a train of thought that continues throughout the book; the mysterious and (to Vicky) frightening topic of death.

During the course of the story, Vicky finds herself in a tangle of three romances; one with Leo, one with Zachary, and one with Adam, whom she is helping with a project on dolphin and human communication (ESP) with three dolphins: Basil, Norberta, and Njord. Vicky discovers a remarkable rapport with the dolphins, a rapport that teeters on telepathy. Also, her grandfather has been hemorrhaging, and Vicky often goes with Leo to pick up blood. There at the hospital, she meets a girl named Binnie who is sick with a type of leukemia and has seizures.

One night, her grandfather starts to hemorrhage and is sent to the hospital. Vicky is on a date with Zachary, and does not know about her grandfather until they come to the dock and see that Leo is not there to pick them up. Once in the hospital, Vicky waits in the emergency room and sees Binnie. Binnie has just fainted because she had a seizure, and is thrust into Vicky's arms as Binnie's mother goes to find a nurse. In Vicky's arms, Binnie has a convulsion and dies. At that moment, she is sent into a wave of darkness, wherein she is trying to hold on to the real world, learning that Zachary left her alone in the hospital, and constantly thinking of Adam. At that moment she feels hands on hers - Adam's. He tells her that she "called" him (meaning with ESP) and he came. During the next day, Vicky is still in a wave of darkness, and no one seems able to get her out. Finally, Adam has an idea. He takes her to the dolphins she works with, and she plays with them, breaking the darkness. At the end of the story, Vicky finally finds refuge in Adam's arms.
