Picking up seven years after the events of "The Friendship Games," Sunset Shimmer is fed up with Equestrian magic, and content to live a normal, though human, life as a private detective. For her, there are no more Elements, no more spells, and certainly no more evils hell bent on world domination. All she wants is a bottle of whiskey, a desk to sit behind, and enough cases to last her a lifetime. Unfortunately, magic has a way of appearing where it's least expected, or wanted. And in her new world, magic is deadly.
A series of magically charged killings leaves the police baffled, and Sunset is reluctantly dragged onto the case when an old lover comes knocking on her door. In order to fight a new enemy, she'll have to deal with old friends and older grudges, and dredge up a past she was certain she'd locked away forever. Throw in government agents, ties to a black market underground, and an inquisitive fashion journalist, and Sunset has never been more in need of a stiff drink, or farther from getting one.
Sucked into a world of new and deadly magic, unsure who she can trust, Sunset Shimmer chases her quarry down a path of ever increasing questions. Who is this mysterious killer? How did they bring magic to this world, and why? And what does the number eleven have to do with it all?
