He was assigned to watch her. He became obsessed with keeping her alive.

Detective Maya Rodriguez has spent three years building the case everyone told her to abandon. Her department buried evidence. Her marriage collapsed under lies. Her badge became a target. Now the only thing standing between her and the men who want her silenced is the last man she should ever trust.

Wei Zhang is Wu Jing's most lethal enforcer?a ghost in the dark, a man trained to kill without hesitation, regret, or attachment. Maya was supposed to be an assignment. A threat file. A liability to monitor from a distance.

Then he watched her bleed for the truth.

Now Wei is in her shadows, in her apartment, in her path, eliminating threats before they reach her skin. Maya knows he is dangerous. She knows protection can become control. She knows a man like Wei does not love softly.

But the conspiracy hunting her is bigger than one dirty badge. Children are vanishing through a network hidden inside law enforcement, charities, and sealed records. To expose it, Maya will have to work with the criminal who terrifies her enemies...and tempts every broken part of her that forgot what safety felt like.

Wei will burn the city before he lets anyone take her.

And Maya will have to decide whether the monster watching her from the dark is her ruin?or the only man ruthless enough to stand beside her when the whole system comes for blood.

Shadow Guard is a dark romantic suspense featuring an obsessive protective antihero, a relentless detective heroine, forced proximity, touch-her-and-die energy, criminal underworld danger, and a high-stakes conspiracy. For adult readers.
