By the author of THE GIRLS I'VE BEEN, soon to be a Netflix film starring Millie Bobby Brown. Nine months. Two weeks. Six days. That's how long recovering addict Sophie's been drug-free. Four months ago her best friend Mina died in what everyone believes was a drug deal gone wrong - a deal they think Sophie set up. Only Sophie knows the truth. She and Mina shared a secret, but there was no drug deal. Mina was deliberately murdered. Forced into rehab for a drug addiction she'd already beaten, Sophie's finally out and on the trail of the killer. But can she track them down before they come for her?
