A new adult novel from Entangled's Embrace imprint... The dead have been waiting for her... Addison Beckett tries hard to pretend she’s normal, but she’s far from it. Since she was six years old, she’s seen the world around her unraveling, as if someone is pulling a thread from a sweater and it’s all slowly coming undone. When she ignores it, it goes away, so that’s what she does. Enter her arrogant-but-hot professor Asher Green. He knows all about her special brand of crazy. In fact, he might be just as nuts as she is. Asher insists that the dead from a parallel dimension are trying to possess the living in this one. And since Addison seems to be the only one who can see these “wraiths,” she just might be the key to saving the world. Addison wants nothing to do with Asher or his secret society, The Mortal Machine. But as their animosity grows, she finds it harder and harder to ignore the chemistry between them. And when she discovers that Machine laws forbid her from touching him, she realizes that’s all she wants to do. Stop the wraiths. Break the rules. Save the world. All in a day’s work. Normal was overrated, anyway.

Her soul remembers his touch, even if she doesn't. With only three days until the wraith king turns the earth into an all-you-can-eat buffet, Addison Beckett is forced to enlist brooding sentinel Asher Green's help to unlock the Mortal Machine. According to the founder, all she has to do is find the sanctuary-the same sanctuary she can't remember because Asher erased her memories. Trying to save humanity while navigating Asher's lies is a royal pain. But the more time she and Asher spend together, the harder her soul tries to remind her what else he's made her forget-that he loves her, wants her, needs her. When she's trapped by the wraith king and forced to pick who will stand by her in the coming battle, Addison is faced with an impossible choice: the sentinel she loves who refuses to love her back, or a powerful stranger who insists they're meant to be together. Her decision will determine the fate of humanity, and once decided, can't be undone.

Since their last battle, life for the Mortal Machine—the secret-society that protects Earth and its inhabitants from dark outside forces—has become almost...normal. For everyone but Addison. The evil she’s imprisoned in her soul has begun eating away at her sanity, and despite her soul mate Asher’s efforts to hold her together, it’s causing painful and terrifying delusions. Consequently, nobody believes Addison's warnings that Marcus, their old enemy, has returned. When Marcus threatens Asher and the Machine, she agrees to find what he seeks—a treasure that, in his hands, could be deadly. If she relies too much on Asher, she knows he’ll likely imprison her, if only to preserve what's left of her deteriorating mind. But if she fails this final test, Earth will fall. So Addison is forced to distance herself from her love, to prevent the life she wants with Asher from being over before it truly begins.
