#1 New York Times, USA Today, and internationally bestselling author Jennifer L. Armentrout returns to the world of the Lux with this steamy, shocking third installment of the Origin series that will leave readers reeling.

He is the darkest star.
She is the burning shadow.
And together, they will bring about the brightest night.

Less than a year ago, Evelyn Dasher was a normal girl, living a safe, rather unremarkable life--a life that was a total lie. Now she's learned the truth about who she was and what she is.

Hidden within Zone 3, she knows that if she loses control of her dangerous abilities again, she not only puts everyone in the secret community at risk, but also the beautiful, deadly inhuman Luc. He will do anything to keep her safe. Lie. Barter. Beg. Kill.

But there are truths that not even Luc can prepare for, and as Evie's abilities evolve, the consequences of everything he's done turn devastating.

Luc is stepping into the darkness. But Evie might already be lost to the shadows.
