"Joseph Delaney's terrifying and brilliant Wardstone Chronicles probes the nature of evil ... The ambiguous relationship between all the characters is as gripping as the gory battle against blood-sucking witches and demons, forcing its hero to continually question whether evil is inherited or chosen" -- Amanda Craig The Times 20080524 "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" Fantasy Book Review 20090110
