"Merry Wrath’s summer plans didn’t originally include an unexpected visit from her old friend, Hilly—a quirky CIA assassin who’s been forced by HR to take her first vacation in…forever. The fact that Hilly chose a small town in Iowa for vacation doesn’t bother Merry or her scout troop (especially since Hilly’s teaching them how to kill a man with one punch), but her former handler, Riley, believes something sinister is afoot.
After all Lana, Merry’s arch-nemesis, is sighted all over town, and when a Chinese operative ends up murdered in her backyard, Merry starts to wonder if Riley is right and Hilly is secretly on the job."
