[1] Published in the United Kingdom through Headline, the novel shifts between the past and present to tell the story of arguments and rivalries between competitive snowboarders that may have led to murder.
Milla is particularly dazzled to meet Saskia and Curtis, sibling athletes and celebrities in the snowboarding world.
Despite sharing a strong attraction with Curtis, Milla begins a brief physical relationship with Brent during the competition.
She deliberately tries and succeeds in ruining Milla's practices and trial runs, fearing that the woman may upstage her.
Fed up, Milla decides to play her own trick and invites Saskia to party with her the night before they are to compete.
The following morning, she drugs Saskia's drink with sleeping pills, intending for it to merely throw the woman off her game by slowing her reflexes.
The reunion is awkward, so they eagerly take part in an icebreaker game that requires them to relinquish their phones and read off cards that have various truths written on them.
It's ultimately revealed that the aggressor is Odette, who had recovered and had even become a biathlete - something undiscovered by the others as they had purposely avoided trying to learn anything about her out of guilt.
Odette correctly assumed that the group was responsible for Saskia's death, but thought that she had been purposefully murdered rather than killed accidentally.
Milla keeps the knowledge of having drugged her water a secret and questions whether or not Brent would have been able to attack Saskia if she were not altered.
