The It Girl – Ruth Ware

A mystery-thriller set in an Oxford college (yay!) Ten years after the murder of her roommate, Hannah begins to suspect that the person convicted of the crime may have been innocent. Was the actual killer one of her Oxford friends? Typical of the amateur sleuth genre, there is rampant suspicion and multiple red herrings. And I can confidently predict that no one will be able to predict the big reveal at the end.
