Weaving seamlessly back and forth in time, That Night by Cyn Balog is a compelling young adult mystery.

One year after her boyfriend Declan Weeks' suicide, Hailey Ward is still struggling to make sense of his death. The past year has not been easy for her since she spent time as inpatient at a psychiatric facility. Although back in school, Hailey is drinking and self-harming in an attempt to stop her emotional pain. She is also still trying to recover the memories she has suppressed about the weeks leading up to Declan's death. Equally confusing is her uneasy relationship with her longtime friend and Declan's stepbrother Kane. But what Hailey finds most upsetting is the troubling discovery of a photo bearing an ominous message in Declan's belongings. Hailey becomes even more convinced her deeply devout boyfriend's death might be murder. But will her slowly returning memories bolster her supposition?

Despite her hospitalization, Hailey has still not come to terms with Declan's death. After seeing the photograph, she becomes insistent in her quest to uncover the truth. Kane is reluctantly helpful but Hailey resents how easily he has moved on. She is extremely distressed by some of the memories that gradually return in the months after the anniversary of his suicide. Is Hailey fully prepared to handle the shocking details of what really happened during the weeks before Declan died?

That Night is an intriguing young adult mystery. Through a series of flashbacks, Hailey's life in the present is cleverly interwoven with her romance with Declan in the past. With an absolutely unanticipated stunning plot twist, Cyn Balog brings this riveting novel to jaw-dropping conclusion. A very engrossing young adult that I recommend to older teen and adult readers due to content such as suicide, self-harming, and underage drinking. ( )
