Then Tony and Tia find that they must escape from men who want to use their special powers for evil. They begin a desperate search to find their true home---which leads them to the strange and mysterious Witch Mountain. (from back cover)

When 13-year-old Elijah Pendleton investigates a strange black cat that mysteriously appeared in his backyard, he finds himself at the doorstep of a woman who will split the understructure of his miserable existence by divulging his true identity as an Enchanter. When she also reveals his parents, whom he believed had abandoned him at birth, may, in fact, be laboring under the callous imprisonment of a power-driven dark ruler bent on revenge and total domination, Elijah feels compelled to do whatever it takes to find them; even if it means stepping through a hidden portal into another world to find them himself. If the long-awaited prophecy is correct, then Elijah’s arrival will bring forth the end to the land’s decade-long reign of darkness. But if the prophecy is to be fulfilled, Elijah will first have to survive the long and treacherous journey that awaits.
