Marked by the Guardian

She wants answers. He controls monsters.

Mark Robertson's fortress of locks and isolation isn't keeping the world out—it's keeping a killer caged. Too much bear, not enough man, and a death sentence ticking inside him. He can't trust the beast, especially not around Julie, whose fearless eyes see through every wall he's built.

Julie just wants her father's research back. She doesn't expect a break-in, a cover-up, or a man whose every breath is a battle for control—and a fierce protector hidden beneath his damage.

When digging into her father's work reveals mad scientists experimenting on shifters, Mark's nightmare becomes real. His time is running out. The enemy wants them both dead. And Mark's control shatters the moment Julie is in danger.

He needs to believe he's not a monster. She needs someone strong enough to stand with her in the darkness.

Together, they'll tear down the conspiracy—if Mark's beast doesn't destroy them first.
