About the first Ormingat book, "Space Race":
"Eleven-year-old Thomas Derwent is moving. Not to another town or city, but to another planet. He and his father have completed their research mission on Earth, and are returning to The Other Place, the planet of Ormingat, where they came from five years ago.

Then Thomas becomes separated from his father, and the decision of whether to stay or to go becomes his. Which will he choose?"

However, boredom changes to anxiety when a letter arrives from Australia announcing that the flat's owner is coming for a visit...

Excerpt:
...Ms. Waugh said in an "Entertainment Weekly," interview with Lois Alter Mark, "I created the Mennyms because the world is too cynical, too lacking in magic. People with dreams are an endangered species, and I wanted to write for them. I don't want the nastiness-the stuff I see on TV."...
