Rarely is the sequel superior to the original, but the second installment of the Blackthorn Key series is just that. Instead of a simple, mildly engaging plot, readers are given a mystery that finds our protagonist (retaining his compelling and entertaining traits of the previous novel) working through a horrifyingly brilliant setting. Having two possible candidates for an antagonist throughout the story is a wonderful strategy to keep readers on their toes, and Sands is still able to shock readers with a surprising plot twist amidst an exciting and emotional climax. The characters, both good and evil alike, are interesting (although one addition to the protagonist's side falls a bit flat) and the plot is extremely entertaining, while still retaining humorous and dark aspects alike.
