Dead by Morning (Rituals of the Night)

Obsession is deadly.

Luna Ketz is no stranger to that. A cynical high school senior caught between her parents' expectations and her own future, she has little time, or patience, for boys. Especially not Chance Welfrey, the odd classmate with an unsettling gaze and a fixation she doesn't return.

Luna doesn't think twice about him... until girls at their school start disappearing. Girls who crossed her. Girls she secretly wanted gone.

A phone call from a long-lost friend shatters what little normalcy Luna has left, pulling her into a terrifying world hidden beneath the veil of sleep. A realm where the boundaries of reality blur and a killer moves freely.

Luna is in danger and although she can avoid the killer during the day, she cannot avoid him in her dreams.
