Nine years ago, with the world's eyes on her, Charlie Colbert fled. The press and the police called Charlie a 'witness' to the shocking events at her elite graduate school on Christmas Eve - events known to the public as 'Scarlet Christmas' - though Charlie knows she was much more than that.
Now, Charlie has meticulously rebuilt her life: she's the editor-in-chief of a major magazine, engaged to the golden child of the publishing industry and focused on never letting her guard down again. But when a film adaptation made by one of Charlie's former classmates threatens to shatter everything she's worked for, Charlie realises how much she's changed in nine years. Now, she's not going to let anything - not even the people she once loved most - get in her way.
