How do you unmask your own killer when everyone wants you dead?

'A twisty thriller with a bloody ending you’ll never see coming.'—Kelly Coon, author of Gravemaidens

Ruby is a scholarship senior at elite Oleander High School with a chip on her shoulder and an attitude to match—which she puts to good use as the infamous local anonymous gossip blogger ReputationKiller. When she’s outed as the voice behind the account, the entire town turns against her.

But after she’s scared witless by a vision of her own ghost dressed in a blood-splattered prom dress, she is faced with an awful truth. Someone out there doesn’t just hate her—they want her dead.

With less than a week until the prom, Ruby starts investigating. Turns out Oleander Bay isn’t the picture-perfect resort town it appears to be. With so many secrets, scandals, and people hell-bent on covering them up at all costs, the murderer could be anyone. Can Ruby beat the clock counting down to prom—and her death—and survive the night?
