Book #19 Killers of a Certain Age by Deanna Raybourn
I've read previous books by Deanna Raybourn and I liked them but this one is the best. Four women assassins, who are about to retire, have a hit out on them. Why? What did they do? Can they find out before they're killed? There's humor and backstory and relationships explored and killing. So much killing. Now this is a group of women I wouldn't mind reading more books about.
