I'm a trained killer who's finally met my match

A Four-Book Series, 18+

Book 4: Ruthless

I’m an assassin who’s finally met my match.
If only he wasn’t such a jerk.
All I want is to be part of the elite taskforce that will defeat our enemy once and for all. The problem? Daryx is the one overseeing the training for the mission.
Some days I’m not sure if I want to stab or kiss him, especially when the silver fox tells me how much he believes in me.
That does something to a girl’s ego.
Now we’re fighting to bring down our enemy, but my feelings are getting in the way. Can I do my job if it means sacrificing him? Or will we both perish because my heart chooses him over logic?
