Under The Mountain

Author: Maurice Gee.
Fantastic book and tv series from one of NZs best known authors.

The show focused on a pair of twins, Rachel and Theo Matheson. While on school summer holidays in Auckland, they were contacted by a man named Mr. Jones, who had met them briefly eight years earlier. This time, Mr. Jones revealed his true identity and mission. He was an alien, sent from another world to recruit the twins in a battle against another race of aliens. These latter creatures were a family of slimy, slug-like beasts who could take on human form. Led by the evil Mr. Wilberforce, the green monsters were now bent on destroying Earth and only the twins' emerging psychic abilities could turn them back.
