Alpha Caellum

Naledi's family was destroyed by the Cosa Nostra Mafia group - also known as the Italian pack. She escaped alone as a child and was trafficked by the Yakuza Mafia pack. 
She soon learns to take care of herself in the dark world of crime and becomes a hired assassin under the pack that trafficked her - burning with a thirst for revenge for her murdered pack.
Things take another turn when she escapes being raped by the Alpha, leaving him half dead and runs away with a bounty on her head. She travels to another territory where she steals from the pack leader and is made to work for five years as an assassin to repay her debt. 
On the final day of her service, Naledi is forced to attend a mating ball, where she meets Alpha Caellum - The head of the Cosa Nostra pack, her enemy's son, and more importantly, her mate. 
Another little detail? Alpha Caellum can't be rejected.
