Plagarma

The magic that holds Plagarma together is weakening. The creatures of the night, that live in a child's nightmares, led by the mythical black hound, Barguest, see their opportunity to take over.
Only a Dream Stalker can take these creatures on, but they died out a hundred years ago. Then there is sixteen year old Tracy. Why does she possess magical powers that other children don't, and who is Donald Tweed?
