Smuggler's Captain

He's on mission of vendetta. She's determined to rescue victims of a ruthless slaver ring. They don't want to need each other as much as they do.
Nadia Koltsova escaped St. Petersburg in the dead of night. Injured and terrified, she found sanctuary in London with a family of her own making. Ten years later, she's determined to protect that family. Taking a midnight stroll into a human smuggler's warehouse? Check. Alone? It was necessary. With only a dagger for protection? She was most definitely prepared.
Captain James St. Clair is searching for the same group of smugglers. They've killed one of his men and he's determined to bring the murderers to justice. At any cost. He does not expect the witty, capable woman with the wicked dagger who insists she's more than capable of taking care of herself. He also doesn't expect to want her as fiercely as he does.
They both need help discovering the missing people. Just perhaps not each other's help.
