Over the Edge[Chloe & Levesque #2] by Norah McClintock

The death of a boy at Chloe’s high school looks like an accident... until Chloe discovers that he was blackmailing several other students. Was it accident—or murder? Chloe’s job as a newshound for her high school paper helps her uncover some startling truths. First, it looks like Daria, the school’s high-profile poet, might have plagiarized some of her award-winning poems. And then it appears that Peter, the writer of the paper’s astronomy column—a boy recently found dead from an accidental fall over a cliff—was blackmailing Daria. And she wasn’t the only one.
