Time has passed since the events of The Last Something Sweet to Bite.
After the incident that came to be known as the Canterlot High Halloween Massacre, Sunset Shimmer was blamed for the arson of the school, as well as suspected of other heinous crimes. When she tells the truth about what really happened at CHS it is inevitable that she would find herself committed to a government facility for the criminally insane.
In a bizarre twist, she ends up under the care of one Dr. Lemon Drop, a human that shares the name of the pony who was responsible for the Candy Mare's existence to begin with. But Sunset Shimmer doesn't have time to puzzle over what his presence could possibly mean. Though she succeeded in destroying the corpse of Pumpkin Patch, the Candy Curse still clings to its final victim... Sunset Shimmer herself.
It wants her mind.
Her body.
Her soul.
And it may only be a matter of time until Sunset has no choice but to let something sweet bite back.
