Emma in the Night is a psychological thriller about two teenage sisters, Cass and Emma, who disappear from their home one night with very little evidence to show where they might have gone. The story begins when Cass returns without Emma three years after their disappearance, and almost immediately you begin to doubt her story about what happened. Throughout the book, you learn more about the sisters' dysfunctional family situation and eventually what caused them to disappear. 
 The story is told in alternating perspectives between Cass and a psychologist on the case. It also includes flashbacks, so there is a lot to follow, but I was absolutely immersed from the start and finished it in one day. Overall, I recommend this for a suspenseful, quick read!
