Kissable Assassin

Felicity Anderson.
Scratch that.
Adriane Collins.
The 16 year-old girl who was kidnapped 3 years ago. Parents dead. No trace of her captors were found. Her first year was the worst ordeal ever endured. Every form of assault and abuse. A love interest massively unexpected, but soon after torn from her grasp.
All to force her to do one thing for them: kill.
And kill.
And kill.
And seal it with a kiss.
