When Regan’s twin brother takes his own life during their senior year of high school, she hides his unopened suicide note for eight years, terrified of what she might find inside.

Raised by their Nanna in a sleepy Vermont town, Regan Byron and her twin brother, Henry, never had it easy, but they always had each other. When Henry takes his own life during their senior year, he leaves behind complete devastation—and a letter. Terrified of what might be revealed in his suicide note, Regan hides the sealed envelope, unable or unwilling to read Henry’s last words. She flees town after graduation, determined to never look back.

Eight years later, Nanna breaks her hip, pulling Regan back home from her career in New York City and bringing her face to face with her past mistakes, secrets, and old friends. The aftermath forces her to a crossroads—leaving the letter unopened and giving into her fear and guilt or reading it and finally letting them go. Regan must decide if she will allow the shadows of her past to eclipse her future.
