Toxic by Nicole Blanchard

A dark, high-heat, high-danger romance where one bad decision turns into a full-blown addiction—and the “villain” is the only one who sees the bruises she’s hiding. Toxic delivers obsessive cat-and-mouse tension, a morally gray antihero with zero boundaries, and that escalating “this is wrong… so why can’t I stop?” spiral.

She thought she escaped her nightmare by marrying the wrong man. Now she’s working as a prison nurse, keeping her head down while she patches up criminals and tries to survive quietly. Until one inmate—ruthless, twisted, and watching her a little too closely—decides she’s his.

He’s brutal. He’s obsessed. And he’s the only person who notices what she’s been trying to hide. His attention should be terrifying. Instead, it becomes a craving. A mistake she can’t quit. When she finally learns what he’s capable of—and why he’s locked up—she runs.

He doesn’t let her get far.
And the forbidden flirtation turns into a hunt… with her as the prize.
