Description: Sadie hasn't had an easy life. Growing up on her own, she's been raising her sister Mattie in an isolated small town, trying her best to provide a normal life and keep their heads above water. But when Mattie is found dead, Sadie's entire world crumbles. After a somewhat botched police investigation, Sadie is determined to bring her sister's killer to justice and hits the road following a few meagre clues to find him.
  When West McCray—a radio personality working on a segment about small, forgotten towns in America—overhears Sadie's story at a local gas station, he becomes obsessed with finding the missing girl. He starts his own podcast as he tracks Sadie's journey, trying to figure out what happened, hoping to find her before it's too late.

Review: Sadie is a powerful, gut wrenching, thriller that will elicit strong emotions from you as you read it. The book has a very simple plot, Sadie Hunter is going to kill the man who murdered her 13-year-old sister, Mattie, but its execution sets it apart from other thrillers. The story alternates between Sadie's first-person point of view as she makes her way across Colorado in search of Keith, who sexually abused her when he dated her mother and who she believes murdered Mattie, and the transcript of a serialized podcast called The Girls by a well established journalist West McCray who is both drawn and repelled by Sadie's and Maddie's story. His interviews with her family and those who crossed her path provide an outsider's perspective to Sadie's actions and interior monologue and always remains painstakingly close to Sadie's present story. The podcast makes the story come alive and expands on book's themes of revenge, ineffective policing, poverty, and addiction and its impact on parenting. 
  Sadie is a precocious survivor. Her mother, Claire, is a drug-addicted, single mother. When Mattie was born Sadie became a de facto parent at the age of 6. Though both sisters had different fathers, Sadie was determined to never let Mattie feel unloved. Her baby sister’s love filled a hole in Sadie’s fiercely protective heart and quickly became her world. Claire favored Mattie, who remained attached to her long after Claire disappeared from their grim, trailer-park home in rural Colorado. Sadie believes that Mattie’s determination to find Claire led to her brutal murder. Without Mattie Sadie has lost her anchor, but her drive for justice, revenge, and hope of preventing other girls like Mattie from abuse and murder propels her into action.
  Sadie is an extraordinary female heroine that I have not seen in a long time in YA thrillers. She is smart, observant, tough, and at times heartrendingly vulnerable. Sadie exempts no one, not even herself, from her unsparing judgment. It broke my heart several times when Sadie immediately questioned a person's kindness, though she was almost always right, but it made me feel incredibly uneasy.
  The book set me on edge and I had to put it aside a few times because of its intensity, but I did feel compelled to find out what happened next. Summers does a fantastic job in not reveling in shocking the reader with graphic and gratuitous detail of the abuse that Sadie encountered, but just the right amount that we can connect the dots. I am still unsure of how I feel about the open ending, perhaps it is selfish of me for wanting a glimmer of hope for Sadie but she really deserves one.
  Sadie is a very timely book especially at a time where female survivors of sexual assault and abuse are being silenced and doubted. This will make an excellent book club discussion and the format lends itself to also be a fantastic audiobook if done well. Unforgettable and one of the best thrillers I have read in a very long time.
