What if everything you believed about yourself was a lie?

Evelyn Harper has spent her life piecing together fragments of a past she can’t fully remember. A dedicated nurse in New York, she tries to maintain a sense of normalcy—until mysterious voicemails from her long-dead twin sister, Amelia, begin to unravel the fragile reality she’s built.

As Evelyn seeks help from the esteemed psychiatrist Dr. Nicole Smardon, memories start to surface—memories of a father who conducted twisted experiments, of a past that doesn’t quite fit, and of a life that may not be hers at all. The deeper she digs, the more the lines between truth and delusion blur.

But when the final piece falls into place, the truth is more horrifying than she ever imagined.

Who is Evelyn Harper? And more importantly…who is she when no one is watching?

What Makes Us is a gripping psychological thriller that will keep you questioning everything until the very last page.
