Olivier

Order of the Black Knights
Olivier Merlo works for a dangerous man. He does what he's told without asking questions because he needs to protect his sister and niece. When someone gives his boss trouble, Olivier does what he does best. It's a routine hit-until the victim's brother starts poking around.
Cody Anders left his family behind a decade ago-along with their wealth and influence-to live on his own terms. Still, he knows his twin didn't die of a drug overdose, and he'll do anything to find the truth. What he uncovers is a conspiracy that will topple his family and leave him staring down the barrel of a gun.
Olivier must decide if he's going to obey orders or free himself from the curse that has guided his hand for centuries. Cody, who challenges Olivier's notion that no one can love him, holds the key to breaking his chains. But when the truth finally comes out, it might be more than Cody can accept.
