Dead by Morning (Rituals of the Night Series)

Obsession is deadly. No one learns that better than Luna Ketz, a pessimistic high school senior. She wishes more than anything to graduate but things don’t always go as planned. Luna quickly finds herself trapped in a web of lies and murders, spun by the least suspected person in her hometown. It’s not long before she realizes she’s being targeted by the person she despises most in the world. When Luna figures out who is behind the killings, things make a turn for the bizarre when she is contacted by a friend she has not heard from in years. It is then Luna realizes she is very much in danger, but although she can avoid the killer in reality, she cannot avoid him in her dreams.
