Fans of Joseph Delaney's fantastic Wardstone Chronicles will need no urging to buy the latest instalment... Gripping, moving and terrifying for anyone of 10+.

No one does terror, and compassion, so well

Joseph Delaney's The Wardstone Chronicles are a series of books that have maintained the very highest standard for nearly a decade. The Spook's Nightmare is another excellent addition to the series. Highly recommended.

The Spook's Mistake is as good as, if not better than the previous four books in the Wardstone Chronicles series. Those who may have been concerned that the quality of the series may begin to wane needn't have feared as it continues to go from strength to strength. 9 out of 10 stars.

Delaney has a talent for creating the most dark and eerie settings and situations, in which the reader becomes totally immersed

fast-paced and suspenseful: plenty of plot twists and character nuances engage the reader throughout (NB: US review, book listed as The Last Apprentice; Attack of the Fiend, pub. HarperCollins)
