A brand new standalone story set in the Ruby Celeste universe!
Seven years, Mona Holmes spent working as a hit person. Seven years of blood; bullets. Bodies.
All that ended when her sister Callie came along. Mona got out; settled down; found a girlfriend, and a life. A real one, away from all that stuff.
But the past has a way of catching upand it does, when Mona comes home to find Callie gone. No sign of forced entry; nothing out of place; not a curtain flapping. Just a message, giving Mona one last job to complete to assure Callie's safe return: to board Castle Adeline, a grand, floating resort run by Zachary Tytheand to kill him.
