I knew she was in trouble the second she looked at me.
Bruised. Terrified. Barely standing.
And when she mouthed the word help through the window of that van, there was no walking away.
I’ve spent my life in dangerous places. Former Special Forces. Private security. Violence doesn’t scare me.
But the woman I pull from that nightmare?
She gets under my skin fast.
Allora Sterling is beautiful, stubborn, and fighting to survive something that should’ve destroyed her. The men who took her hurt her in ways that make my hands shake every time I think about it.
Now someone wants her back.
And after the traffickers tear apart her condo looking for her, I take her home with me because it’s the only place I know I can keep her safe.
One apartment.
One bed.
One broken woman who still finds the strength to smile at me.
I should keep my distance.
Instead, I become obsessed with making her feel safe again. Feeding her. Holding her through nightmares. Touching her like she’s something precious instead of something broken.
But the deeper we fall, the more dangerous things become.
Because the men hunting Allora aren’t random criminals.
This is personal.
And when they take her from me a second time, they make one fatal mistake—
They leave me alive.
Now there’s nowhere on earth I won’t go, nobody I won’t destroy, to bring her home.
Even if I have to burn the whole world down to do it.
Heart-pounding danger from start to finish! A familiar face from Mizera’s Royal Protector’s series is kicking off her brand new Shadow Security series. Fans will quickly recognize Landon Grimshaw as well as his family and cohorts Courtney, Daniil, Rage, Chaos, etc. as they set up shop with a new security firm and are quickly thrust into the middle of more than they were bargaining for. The characters are well developed, the pace is intense and addictive and the romance worming it’s way into the business of things is refreshing. I highly enjoyed the start of this spin-off and can’t wait to see more of the guys find their true love! I especially need to hug on Chaos soon!
Allora Sterling is an interesting character who can thank her lucky stars Grim was in the right place at the right time to see her cry for help. She’s fairly complex in that she’s successful and independent but she has a past in a sheltered, controlling life that she has worked hard to free herself of in the best way she can. The danger surrounding her brings that life to her bedside again … and a part of her wants the connection, but most of all she wants clear. There is a twist that really brings things to a head and changes her world.
I highly enjoyed Landon and Allora and recommend their story to anyone who enjoys a bodyguard trope filled with danger, high intensity and a sexy happily ever after!
