From Greer Hendricks and Sarah Pekkanen, the authors of the top ten bestseller The Wife Between Us, comes An Anonymous Girl - an electrifying novel about doubt, passion and deadly obsession . . .

Seeking women ages 18-32 to participate in a study on ethics and morality. Generous compensation. Anonymity guaranteed.

When Jessica Farris signs up for a psychology study conducted by the mysterious Dr Shields, she thinks all she'll have to do is answer a few questions, collect her money and leave.

But as the questions grow more and more intense and invasive, and the sessions become outings where Jess is told what to wear and how to act, she begins to feel as though Dr Shields may know what she's thinking . . . and what she's hiding.

As Jess's paranoia grows, it becomes clear that she can no longer trust what is real in her life, and what is one of Dr Shields's manipulative experiments. Caught in a web of deceit and jealousy, Jess quickly learns that some obsessions can be deadly.
