Read the bonus chapter (available on Colleen Hoover’s website). It will change your mind about the ending entirely. Have you read Verity ? Do you believe Verity’s letter, or do you think she was lying? Let me know in the comments below!

What she finds in that office isn't just plot outlines. Hidden in the back of a drawer is a manuscript titled "So Be It" —an autobiography Verity never intended for the public. Inside those pages is a confession so vile, so disturbing, that it changes everything Lowen thought she knew about the family.
