We Did Nothing Wrong - Hannah Jayne

Lia thought of the dark night, of the broken street light.
Had Diana gone out to meet her? Had she been waiting for her, alone in the park?
Or had someone been waiting for Diana?
Lia and Diana are the "it girls" of Empire Hill High. Their lives are perfect....until Diana disappears and the rumors start flying.
Everyone thinks Diana is a runaway, including the police. Lia is secretly convinced it's all a prank. Then she finds a crushed red rose tied with a candy-cane ribbon where Diana went missing. And next to it, a note:
YOU
It's the same ribbon Lia's received on gifts from a "secret admirer." Did someone come for Diana that night? And will Lia be next?
