Kai's mother eases her grief with what Kai terms the 'death checklist', busying herself with funeral arrangements and a wake. Kai's father retreats to his study, for drink and to hide within himself. Because of this, Kai feels more alone than ever, with her sister (her main confidant) now gone. When Kai's grief finally devolves into a state where she almost takes her own life, her parent's send her away to a grief camp.
It is at this camp that Kai meets other teenagers who have suffered a similar loss. Their shared experiences help her to open up, to allow others to know what she is feeling and understand it, and to finally forgive her sister. I found it petering a bit at the camp section of the book, where it became a bit on the unbelievable side with how quickly love was formed. However, this book was well written, emotional, painful, and marked with moments of happiness. For Kai, and her family, her sister's death will always play a large part in their lives, but they must learn to navigate life knowing she is always with them, even though she is gone; this is their new normal. Like Marco, the camp counsellor says, "Not moving on, moving forward. There's a big difference."
