Pretty much every one of the characters was immediately dislikable. Faye's point of view was an enjoyable, to a point, as a lens through which to watch the plot unfold though she, too was similarly flawed to her peers with her voluntary isolation and her unacted upon longing for friends. The plot and interpersonal conflict was engaging enough that I continued on reading despite the unlikable nature of the characters. Jurczyk has a way of exploring vulnerability and desperation in her characters, their grisly deaths and injuries, and their mourning rituals. The twist ending was very unexpected, but made sense given what we are shown of Kip.
No one in this book is innocent, and there are questions of guilt left unanswered in such a way that no one is absolved.

Faye imagines a life for herself with Umu as her best friend, replacing Ro so quickly after his death at her hands, because she's read so much about bonds that form over shared trauma. It's unclear whether or not Davey killed Soraya because she got the permanent job over him. He decapitates Mary and Faye doesn't intercede when the fight between Mary and Davey leads to Umu's death. The two survivors are killers by the end of the night and while neither is in trouble with the law when they're taken out of the bloodbath that is the basement, readers are left hanging whether or not they will be held accountable for the carnage. Kip having licked one of the green books for a meme, honestly makes sense given his entitlement and lack of care for the work others are doing beyond what his name can give him access to. My only issue with this is that Kip goes from zero to sixty in his cruelty before disappearing. It seems like something he's kept under wraps, with the exception of his entitlement, throughout the flashbacks later in the novel, as opposed to being a side of himself he'd share with five other people. I wasn't able to find anywhere whether erratic behavior, delusions of grandeur, etc. are symptoms of acute arsenic poisoning. Depression, anxiety, and cognitive impairment are symptoms of ongoing arsenic exposure. Maybe he was just a dick. Faye climbing into the collapsed shelving and hiding near Soraya's corpse to keep away from Davey after he kills Mary is such a sad, memorable scene.
