RaveForeword ReviewSara Kersting’s Duty to Warn is a finely tuned, suspenseful chase story.The novel deftly weaves between its three leads’ perspectives. These shifts between people and through time are jarring in a way that mimics Percy’s recollections. Each character’s section shines and is full of personality ... The author draws upon her career in the mental health field to great effect. Professional jargon is eschewed for a taut narrative that offers up ample information without hampering the tense plot’s momentum ... Secondary subplots show Malden and Nielsen as dynamic and painfully real people ... Duty to Warn is captivating.
