This is book number 7 in the Cain Casey series.
For Cain Casey nothing is more important than family, and having hers close--Emma, Hayden, Hannah, and the new baby--is as near as she'll get to true happiness. But enemies who lurk in the shadows threaten more than just her business, forcing her to question whether the biggest threat comes from having it all.
As Cain continues to search for lingering adversaries like agent-turned-drug dealer Anthony Curtis, the FBI is hot on her tail and will stop at nothing to lock her away. Add the Russian mob into the mix and it might be too much to handle. It will take a transformation into the devil incarnate for Cain to keep those she loves safe and to hold on to her rightful place as the head of the family.
