Things can never be the same again.
After a long journey and a hard battle, the Spook and his apprentice,
Tom Ward, have returned home. But the county has been overrun by enemy
soldiers. The Spook's house is in ruins, the boggart protecting it has
fled, and the malicious witches imprisoned in the gardens have escaped.
Tom, Alice, and the Spook must flee, too, across the ocean to the island
of Mona. And it's on Mona that this small band fighting against the dark
will face an old enemy grown terrifyingly powerful. Will they be able to
vanquish an evil that crawls beneath the ground itself? And at what
cost?
