Merlin's Keep - Madeleine Brent

Jani, the strange and lovely heroine, has been brought up in a remote region of the Himalayas in Tibet by a runaway English soldier. Both Jani’s past and that of her soldier protector are shrouded in a mystery that grows ever deeper for Jani when the foreign demon on a black horse comes from the south to take her away to a new and frightening world—a London orphanage. Later, when she moves on and finds the Woman in Red, Jani becomes one of the family in a Hampshire household. And it is here that her past is gradually uncovered. She becomes locked in a macabre struggle, long prophesied by the High Lama of her Tibetan youth, against the strange and terrifying powers of the Silver Man.
