It was my first book by Riley Sager and it won't be my last one!
 The story follows Charlie and Josh who are both meeting on a campus ride board looking for a ride home to Ohio. Charlie is devastated over her best friend's death, who was murdered by a serial killer and Josh is on his way to care for his ill father. During their shared drive Charlie is having her doubts and is becoming very suspicious about Josh. 

I really enjoyed the claustrophobic atmosphere. The majority of the book is taking place in the car. At night it definitely made me a little uncomfortable! I found the story very easy to follow and I also enjoyed the author's writing style. I absolutely flew through this book!
 If you plan on reading it, stop reading this review now as I think it is best to go in blind!
 The thing I enjoyed most about the story were all the old movie references. Like the main character I had a time where I just lost myself in movies from the 40s-60s. Those movies have a special magic to themselves and I totally get the adoration Charlie has for them. 
I sometimes didn't understand why Charlie did or didn't do certain things but it still worked for me in the end, although I can see why people get annoyed by her decisions. The book is full of twists and turns which I enjoyed most of the time. The motives of the killer and the killer themselves felt a little off to me but I still very much enjoyed that book!
