Prudence Perry is a third-generation Ladybird Scout who must battle literal (and figurative) monsters and the weight of her legacy in this YA paranormal. Sixteen-year-old Prudence Perry is a legacy Ladybird Scout, born to a family of hunters sworn to protect humans from mulligrubs―interdimensional parasites who feast on human emotions like sadness and anger. Masquerading as a prim and proper ladies' social organization, the Ladybirds brew poisons masked as teas and use knitting needles as daggers, at least until they graduate to axes and swords. Three years ago, Prue’s best friend was killed during a hunt, so she kissed the Scouts goodbye, preferring the company of her punkish friends lovingly dubbed the Criminal Element much to her mother and Tía Lo’s disappointment. However, unable to move on from her guilt and trauma, Prue devises a risky plan to infiltrate the Ladybirds in order to swipe the Tea of Forgetting, a restricted tincture laced with a powerful amnesia spell. But old monster-slaying habits die hard and Prue finds herself falling back into the fold, growing close with the junior scouts that she trains to fight the creatures she can’t face. When her town is hit with a mysterious wave of demons, Prue knows it’s time to confront the most powerful monster of all: her past.
