Escape to Witch Mountain by Alexander Key, 1968.

This is the book that the Disney movie of the same name was based on.  In fact, there have been three movie renditions of this book, although the 1975 Disney version is the one I know the best, and it’s the only film version to call the children by their original book names, Tia and Tony (other versions use the names Danny and Anna or Seth and Sara).  There are some major differences between the book and each of the the movies.  For one thing, most people in the book think that Tia is mute because she speaks at a frequency that ordinary humans can’t hear.  Only her brother, Tony, can hear what she’s saying.  She uses the little case with the double star emblem that she’s had ever since she can remember to carry paper and pencils so that she can write messages in order to make herself understood by other people.  In the 1975 movie, Tia can speak to Tony telepathically, but both children can speak aloud normally and be understood by everyone.

When the book begins, Tia and Tony know that they’ve always been different from other children.  They look different: they have olive skin, pale hair, and very dark blue eyes, which is a somewhat unusual combination. They can do things that others can’t: Tony can make things move with his mind, Tia can open locks without using a key or any other device, and only Tony can understand the strange way that Tia talks that others can’t even hear. They can’t remember any other home than the one they had with Granny Malone, the woman who adopted them, but now that she’s dead, they find themselves wondering who they really are and where they came from.  Tia has shadowy memories of a time before they came to Granny Malone, when they were on a boat and something bad happened to them, but she can’t quite remember what.

With no known relatives to go to, the children are taken to an orphanage, Hackett House, after Granny Malone’s death.  It’s a tough, inner-city environment, where no one has any patience with Tia and Tony’s strangeness.  However, when the children from the orphanage are sent to Heron Lake Camp in the mountains during the summer, a nun recognizes the double star symbol on Tia’s case as one that she had seen before on a letterhead, giving the children their first clue to finding their origins.

Then, a figure from one of Tia’s memories, Mr. Deranian, comes to the orphanage to claim them, saying that he’s their uncle. The children can tell that he’s no relative of theirs. They run away to see a kind priest, Father O’Day, an associate of the nun they met earlier. Father O’Day is the only one who believes the children when they talk about what they remember of their past and isn’t frightened by their strange mental powers. When the children show him a map that they found in a hidden compartment in Tia’s case, he offers to help them find the place marked on it and, hopefully, someone who knows who the children are and where they belong.

The book is currently available online through Internet Archive.  There is a sequel to this book which was also made into a movie, Return from Witch Mountain.

My Reaction and Spoilers

As the children and Father O’Day try to elude Deranian and the others who are chasing them, more of Tia’s memory returns. The children are from another planet. Years ago, their planet was destroyed when it crashed into one of their twin suns. Their people, who call themselves the Castaways, knowing that their planet would not be habitable for much longer, had already begun looking for a new home. Earth was the nearest habitable planet, so some scouts arrived early and began to create a home for them in the mountains of North America, which was the closest environment to their former home.

Unfortunately, when the rest of the children’s people came to Earth, the group that Tia and Tony were with crashed in Eastern Europe. The book was written during the Cold War, so the place where they crashed was controlled by Communists. When the Communists realized the powers these people possessed, they planned to make use of them themselves. One of Tia and Tony’s people escaped with the children and managed to get them aboard a ship heading for America. Before he died of a gunshot wound, he placed some money and a map in Tia’s case so that the children would know where to find the rest of their people. However, the children were traumatized by the experience, and Tia blocked the memory out of her mind. The ship’s captain, upon reaching the United States, gave the children to Deranian, a friend of his. Deranian, not knowing who the children were or what powers they possessed, gave them to Granny Malone to raise. Later, he found out about the children’s abilities from his contacts in Eastern Europe and tried to get the children back.

In the end, Father O’Day manages to reunite the children with the rest of their people, who take them to the community they have built on Witch Mountain, a place where locals are too superstitious to go, named for the odd things they’d seen there when the Castaways first arrived. Father O’Day plans to go there and join the community along with the children someday.

In spite of the Communists being enemies during the Cold War, Tia and Tony say that one of the reasons why their people had trouble establishing themselves in America at first was that they were unaccustomed to the idea of having to buy land to live on.  On their world, no one owned land; land was just there for people to live on and care for.  Their people’s early scouting expedition included selling pieces of their ships in order to raise enough money to buy some land in order to build their community.  Father O’Day is impressed with the Castaways’ commitment to the common good of all people and unselfish sharing.  So, although the oppressive Communist regimes of the Cold War are enemies in the book, some of the ideals of sharing and supporting the common welfare of everyone are still attractive ideals in the book.  The implication in the book is that Tia and Tony’s people are socially as well as technologically advanced and have created the best of all possible systems, a blending of ideals to create the ideal balance.

I can understand why the movies did not include Tia speaking at a frequency no one else can hear and appearing mute.  That would be difficult to show in a movie that relies on characters being able to communicate with each other, and it makes sense to replace it with an ability to communicate telepathically by choice instead.  None of the movies include the Cold War references that were present in the book, and the character of O’Day or the person who helps the children to reach Witch Mountain changes from movie to movie, but the plot of the 1975 Disney movie is still the closest to the original book.
