Vipers & Roses by P Mulholland

Hit One.
There were four of them on that summer’s night two years ago. And one of me.
Wracked and ruined, bloodied and scorned, I survived. But I am not defeated. I will not be defeated. Today is the day I step out of my facade and take revenge on the first name on my list.

The Lion.
In stealth, as I relentlessly pursue my target, three men pursue me – the handsome silver-haired detective who saved me, his son, a smoldering swim star who helped heal me, and the charismatic yet dangerous thief who trained me.
