How can a living nightmare bring such sweet dreams? Mara Vance never thought her “useless” psychology degree would lead to studying an actual monster. Subject X-13, aka “The Nightmare,” is armed with sharp teeth, claws, and a constantly shifting form… yet Mara finds the huge shadow creature as intriguing as he is terrifying. But as Mara studies him, she soon realizes that the Nightmare is far more intelligent than her shady superiors say he is. And every night, she indulges in twisted fantasies about the same monster. What happens in her dreams stays in her dreams - right? Everyone says he’s nothing more than a monster. But when dream and reality collide, Mara must decide how much she’s willing to trust him - and herself. Will she risk setting him free, or will she lose him forever?

Can a dead heart learn to beat again? After dropping out of med school, Lucy Sullivan thought her skill with a scalpel would only be useful for her hobbyist taxidermy. But life takes another unexpected turn when she becomes the doctor for a most unusual one who’s already dead. Or undead, rather. Subject X-14, “The Revenant” - aka Victor - may be a collection of stitched-together corpses with a hunger for human flesh, yet Lucy soon finds herself grappling with unexpected fondness for her patient. In spite of her general fear of getting close to people, she wants to make him happy just as badly as she wants to cut him open and figure out what makes him tick. But when Victor uses her as a hostage and kidnaps her, Lucy becomes a pawn in his plot to take out his cruel creator. They say if you seek revenge, you should dig two graves - and with Lucy caught up in this scheme, it might just be three. Can she save Victor before he loses himself to his desire for vengeance, or will he drag her down with him?

Could her imaginary friend be a real threat? Daisy Dumont tries so hard to be normal. She doesn’t talk about the night her parents were murdered, or the fact she can’t remember it. She certainly doesn’t talk about her imaginary friend who disappeared shortly afterward. Then the MRF calls. The research facility finally admits that they took her former friend - and now they want her help to save him. Daisy is the only one who can see Subject X-15. She once knew him as Dorian, but the volatile monster in the cell bears little resemblance to the shy apparition who lived under her bed. And even with a new researcher willing to hear his side, Dorian won’t - or can’t? - explain that he didn’t kill Daisy’s parents all those years ago. An experimental treatment could unlock what she’s forgotten, yet the more she dredges up the past, the harder it becomes to pretend she’s anything close to normal… If Daisy doesn’t find the truth about her lost memories, Dorian will fade from existence. But if she does, she might end up in a cell herself.
