He was supposed to guard her. Instead, he’s going to ruin her for any other man.

Deputy Liam Morgan has one job: keep his hands off the Chief’s little sister. Fiona Thorn is twenty-one, a brat with a badge-in-training, and officially off-limits. She’s a walking career-killer, a forbidden fruit wrapped in a uniform that fits her in all the wrong ways. Liam was told to protect her, to watch her back at the station—not to want her with a hunger that burns every rule to ash.

Fiona knows exactly what she’s doing. She’s here for an internship, but her real mission is to make her overprotective brother lose his mind. And using the tall, brooding Deputy with the dark eyes and the lethal hands is the perfect way to do it. She thinks she’s in control.

But the game turns deadly serious. In the shadows of the locker room and the silence of the night shift, Liam is done being the "good deputy." He’s a man of secrets and sins, and he’s decided that if he’s going to hell for touching her, he might as well make it worth it.

Fiona started this as a fake provocation, but she’s about to learn that when you push a man like Liam to the edge, the only way down is surrender.

High heat, obsessed Alpha hero, and a HEA that will set your Kindle on fire.

Tropes: Forbidden love, brother's best friend/boss's sister, age gap, forced proximity, possessive alpha.

One-hour read. No cliffhanger. Guaranteed HEA.
