You Are Not Alone

Greer Hendricks and Sarah Pekkanen are friends and the co-authors of four best-selling suspense thrillers. In addition to You Are Not Alone, they have co-written the novels The Wife Between Us (2018), An Anonymous Girl (2019), and The Golden Couple (2022). Their works are known for featuring strong female protagonists that interrogate the dark side of human nature and human relationships.

Although Sarah Pekkanen has co-written four novels with Greer Hendricks, she is also a best-selling solo author, known primarily for domestic thrillers that often probe the gap between appearances and reality. Originally trained as a journalist, Pekkanen’s first novel, The Opposite of Me, appeared in 2010, focusing on a fraught relationship between twin sisters. The Ever After (2018) examines a crumbling marriage and shares with You Are Not Alone a thematic interest in the gulf between appearances and reality.

Greer Hendricks also has a journalistic background. She holds a Master’s degree in journalism from Columbia University but has spent much of her career in publishing. She worked for nearly 20 years at Simon and Schuster, both as an editor and as a vice president. Hendricks has not published novels on her own, but she has written two popular short stories.
