Sadie's sister, Mattie is dead; killed by someone who picked her up as she was headed out of town to find her mother living in LA. Sadie can no longer live, knowing that the man she believes is Mattie's killer is still out there. When she takes what money she has left and goes on the road to find him, she unearths clues and ugly secrets.
In Sadie, we get two different perspectives in alternating chapters; one is Sadie's perspective while the other is in the form of a podcast called "The Girls," which details an investigation being conducted by journalist, West McCray. Between the two, we get a picture of Sadie's and Mattie's unhappy lives living in a trailer court with a drug addicted, alcoholic mother, who eventually runs off leaving Sadie at thirteen years old to raise her younger sister. This is just an extremely sad story that offers no hope or redemption. Overall, Sadie is well written and full of emotion, but a much too depressing ride to make it an enjoyable read.
