A "moving, astounding, and totally unsettling" (Caroline Leavitt, New York Times bestselling author) literary debut following two patients in recovery after an experimental memory drug warps their lives.

Lucien moves to Los Angeles to be with his grandmother as she undergoes an experimental treatment for Alzheimer's using the new drug, Memoroxin. An emerging photographer, he's also running from the sudden death of his mother, a well-known artist whose legacy haunts him.

Sophie has just landed the lead in the upcoming performance of La Sylphide with the Los Angeles Ballet Company. She still waitresses at the Chateau Marmont during her off hours, witnessing the recreational use of Memoroxin?or Mem?among the Hollywood elite.

When Lucien and Sophie meet at The Center, founded by an ambitious yet conflicted doctor to treat patients who've abused Mem, they have no memory of how they got there?or why they feel so inexplicably drawn to each other. Is it attraction, or something they cannot remember from "before"?

"Contemplative and wonderfully evocative, finishing The Shimmering State is like waking from a dream, where you reenter the world with fresh eyes and wonder at the frailty of your own memories" (Jessica Chiarella, author of The Lost Girls).
