After her little sister, Hope, is brutally murdered by their father around the anniversary of her mother's suicide, Ryan tries to find some sense of normalcy in this world that is now filled with grief. With no other support system but her father's ex-girlfriend (now legal guardian), her best friend Skylar who has her own problems, and her childhood friend turned boyfriend Brodie with a heart of gold, Ryan navigates her junior year of high school. As she finally starts to feel a sense of a routine in her messed up world, her classmate turned sorta friend Emma goes missing the night she was at a party Ryan invited her to. With the police questioning her, Emma's weird friend Kellan sniffing her hair, and these terrifyingly detailed letters describing her sister's murder, it seems for Ryan that normal died with her sister.
