The Devil You Know

Cain Casey has much to be thankful for-a loving wife in Emma, three beautiful children, and an ever-expanding family. Her business continues to grow, giving her the power to keep it all safe, but is it? Unknown federal agents are not playing by the government's rules, and the Russian mob comes seeking revenge for the losses Cain's inflicted. Cain and Emma have agreed to partner with the local feds to root out their rogue agents, but their goals for the endgame are completely different. Cain wants to remove the threat the way she knows is best-permanently. There is also Nicola Antakov, who she plans to handle the same way.
Cain Casey is the devil you know. She loves her family and will do anything to keep them safe and whole.
