Luce Potter lives by a code of honor. Push her and she shoves back, harder. There’s only one problem: Luce has just found out that revenge is a knife that cuts both ways. Now that her lover Brooke has survived the attack on her life, Luce has only one thing on her mind, and his name is Frank. Unfortunately, someone walks into her life that she didn’t see coming.

Brooke Erickson has survived an attack so brutal it’s left a permanent scar on her soul. All she wants to do now is go home and finish recuperating with her lover, Luce Potter, by her side. An unexpected event puts Brooke at the head of the Yakuza family. Can she command the respect necessary to lead it through the crisis?

Luce and Brooke’s worlds are upending. Can each do what’s necessary to survive and return to a new normal?
