For fans of Gayle Forman, Jennifer Niven, and Jandy Nelson, this innovative, heartfelt debut novel tells the story of three teens and how they cope with death and loss in the social media age.     AUTUMN: On a cold winter's night, Autumn skipped a class party to flirt with her best friend Tavia's brother, Dante. That night, Tavia was in a fatal car crash. Now, Tavia's Insta feed is flooded with comments from classmates who barely knew her, and Autumn can't decide if she's furious with these people for pretending they loved Tavia like she did, or furious with herself that she can't quash her feelings for Dante, even still.      SHAY: After a five-year battle with leukemia her twin sister Sasha finally passed away, and now, she and her mom don't quite know how to live together, without someone to take care of. At least her mom doesn't know about Sasha's queued Tumblr posts, appearing months after her death. She's being digitally haunted by her twin, but she can't stop reading.      LOGAN: His ex-boyfriend and first love committed suicide— but he doesn't understand how Bram, whose last year of happy-go-lucky YouTube celebrity had put him on cloud nine, could have been that depressed.      Each alternating perspective of these teens shows how we struggle with how social media plays a huge role in our lives—and deaths. As their lives begin to intertwine, we'll find they're all looking for the same thing: closure.
