Thrall (Cat Adams) Books in Order

Thrall is a three-book paranormal series by C.T. Adams and Cathy Clamp, writers also known through the Cat Adams byline. It follows Kate Reilly, a courier whose life is overturned after a run-in with the Thrall, a species of parasitic vampires. These vampires are not distant aristocrats or glamorous love interests. They are invasive, dangerous, and deeply interested in control.

Kate survives a Thrall bite, but survival comes with a complicated new status. She is labeled Not Prey, meaning the usual rules about who can feed on whom no longer apply in a straightforward way. Her psychic connection to the Thrall makes her valuable to them, and it also leaves her exposed to forces she does not want anywhere near her mind or her family.

Kate wants her life back. The vampires have other plans.

The first book, Touch of Evil, introduces the basic danger and brings Tom Bishop into Kate's orbit. Tom is a firefighter and a werewolf, and his steadiness gives Kate one person she can rely on while the supernatural pressure mounts. Their relationship is important, but it develops in a world where every alliance has consequences and every promise may come with a hidden cost.

Touch of Madness raises the stakes by putting Kate under legal and personal pressure while threats keep closing in around her. Family concerns become especially urgent, and Kate is forced to work with people she has every reason to distrust. By Touch of Darkness, the old protections around her have weakened, leaving her to face an enemy who can change the rules of the conflict.

The trilogy has a close, tense feel. Kate does not have the distance to watch the supernatural world from the outside. It has entered her body, her relationships, and her home life. The central question is not just whether she can defeat a particular villain. It is whether she can remain herself when powerful creatures keep trying to define her as prey, property, or a useful weapon.

The vampires are the problem, not the fantasy of the problem.

That darker approach sets Thrall apart from the authors' shapeshifter stories. There is still romance, action, and a strong sense of loyalty, but the mood is more uneasy. The books deal with bodily autonomy, coercion, fear, and the cost of asking for help from someone who may later expect payment.

Read Touch of Evil, Touch of Madness, and Touch of Darkness in that order. Kate's relationships and the larger battle with the Thrall build directly from book to book, and the trilogy works best as one continuous story.
