Nobody enters here after dark. Come back in the morning . . . if you're still breathing.

Thomas Ward is the seventh son of a seventh son, and apprentice to the local Spook. He has battled boggarts, witches, and the most powerful evils of the Dark. But his most trying task is yet to come.

When Tom and the Spook are deceived by one they trust, they find themselves in the most terrifying danger yet. Blood-hungry creatures have invaded a sleepy village. Tom can save the Spook - and the whole county - but only by betraying one of his greatest allies. With everything on the line, Tom must have the courage to stand and fight, and to face a choice that could break his heart.
