If Backwoods Ripper had you chewing your knuckles in suspense, Retribution Ridge certainly will not disappoint. But the tension has a deeper psychological twist in Anna Willett's later book, which has the reader sharing in the entrenched distrust that exists between the two sisters at the centre of this story. This is a book that taps into our own fears of past wrongs, which delivers an exciting, pacey read with the kind of eerieness and impending threat about it that will have you reading long past bedtime.
