The Spook's Blood: Book 10 (The Wardstone Chronicles, Band 10)

As his final battle against the Fiend draws near, time is running out for the Spook's Apprentice, Thomas Ward. The Fiend will send his greatest servant, Siscoi - a Vampire God more ferocious than anything Tom has yet faced. Isolated and afraid, Tom must risk his life to prevent the evil beast from entering this world, even as he learns that the final destruction of the Fiend may involve a sacrifice more terrible than he can imagine ... The tenth installment in the chilling Wardstone Chronicles series should not be read after dark!
