Decided on a 3 star for this book because the first half had me very entertained and I really enjoyed the whole concept of possibly being stuck in a car with a serial killer. I didn’t rate it higher because the amount of times Charlie could’ve escaped but didn’t was way too many which was kinda dumb and the second half of the story started to go in a direction that felt unrealistic to me. I definitely want to read more thrillers that take place in the car/on a road trip though!
