A young woman with little memory of her past is thrust into a world of fighting, guns, and killing after mobsters burn down her sister’s flower shop. An action-packed series about a sleeper agent and her quest for revenge—and answers.

Luna can barely remember the past five years of her life. Her older sister promised to help her make new memories—and then vanished without a trace before she could follow through with her promise. With nothing but a few ragged memories to cling to, Luna dedicates herself to the flower shop her sister left behind until the day it goes up in flames, plunging Luna’s world into bloody chaos.

Luna doesn’t know how she got so good with a gun, but one thing’s for sure: She will not forgive the men who destroyed her sister’s shop. Will Luna’s deadly skills and hunger for revenge be enough to punish the most dangerous men in the city? And just where did her newfound skills come from?
