Chocky: Matthew Gore is an intelligent boy chosen by a mysterious extraterrestrial visitor to be a source of information about life on Earth.

Chocky's Children: A year has passed since Matthew said goodbye to his alien friend, and in the summer holidays he meets Albertine, a mathematical prodigy, with whom he discovers he can communicate telepathically. One day Chocky returns to warn him that they are both in danger. When he returns to tell Albertine, he finds she has disappeared.
Chocky's Challenge: Chocky, an invisible being from another world, has come into Matthew's life. His powerful knowledge has aroused a great deal of interest from the military, and they are willing to take drastic action if they don't get what they want.
