A jawline held tight.'I quite like Jenni. What about you?'I don't reply. Carly and Rob, Jenni and Craig. Two couples, four friends. Betraying each other. Wanting each other. All of them have access to prescription drugs through the medical practice where they work, and all of them are fighting their own demons. But can any of them be trusted? And when the lies begin, can they ever be silenced?
