Angels
To the women her brother traffics, Nikita Federova is the devil in skinny blue jeans, the woman who controls their destiny, every bit as despicable as her brother.
Yet the reality is that Niko lives in a hell of her brother’s making, as trapped inside his evil world as they are.
All she can do is try and protect them and her young son any way she can until the day she can finally escape Ilya’s control.
But with no money and no passports, she knows her chances of getting away range from nought to zero.
After spending all his adult life in the Marines, Hollywood and his best friend Kellen Davis have ditched the uniform to go and save the world on their own terms.
Moving to London to join the Guardians is Hollywood’s idea of a dream job, fighting evil, saving damsels in distress, and all while being adopted into the Alpha-Stalwart family. Being hand-picked for the job by the Alpha-Stalwart directors is just the cherry on top.
When his team are tasked to go undercover with a gang of human traffickers, Hollywood thinks the hardest part is going to be hardening his heart to cope with all the horrors they’re likely to witness.

The last thing he expects is to lose it altogether.
