Flower's Beast is book one in the Agency Soldiers series but can be read as a standalone.
Nikolai
The Agency gathered children like me into their society, ones that were either unwanted or so tainted with evil that they never would have survived in the real world. Others were raised to be cunning and sly, but I was trained to be a weapon. Only brutality ran through my veins. Even after the Agency crumbled under the power of the soldiers they created, I still thought that's all I'd ever be. If I'm pointed at a target, I kill or capture, never failing.
Until her.
She awoke something within me. A strength strong enough to fight the darkness in me that I'm much more familiar with. But both sides want her in a way I've never craved before.
I may not understand why...but everything she is, was made for me.
Powerful people in this world want her wiped from the map, but they'll have to get through me first.
If anyone is going to hurt her, it'll be me.
Ana
Twenty years ago, I woke up in a hospital, my body and mind damaged, only knowing my name. No one was looking for me.
As I spent most of my childhood with no one looking out for me, my upbringing was too treacherous to truly focus on my lost memories. Even as an adult, my battered brain never let me live that much, keeping me trapped in my city, forcing me to hide from...something. I can't remember what it is though.
Someone from deep in my lost memories wants me dead, but they made a mistake. The man they sent has much different plans for me. My predictable, hidden life is over. It's time to run now.
The Beast at my back is getting closer.
